2.0 Applicable standards and reference documentation  
The drives documented in this manual have been developed as system peripherals to the highest standards of design and  
construction. The drives depend on host equipment to provide adequate power and environment for optimum performance  
and compliance with applicable industry and governmental regulations. Special attention must be given in the areas of  
safety, power distribution, shielding, audible noise control, and temperature regulation. In particular, the drives must be  
securely mounted to guarantee the specified performance characteristics. Mounting by bottom holes must meet the  
2.1  
Standards  
The Seagate 1200 SSD family complies with Seagate standards as noted in the appropriate sections of this manual and the  
Seagate SAS Interface Manual, part number 100293071.  
The drives are recognized in accordance with UL 60950-1 as tested by UL, CSA 60950-1 as tested by CSA, and EN60950-1

3.0 General description  
Seagate 1200 SSD drives provide high performance, high capacity data storage for a variety of systems with a Serial  
Attached SCSI (SAS) interface. The Serial Attached SCSI interface is designed to meet next-generation computing demands  
for performance, scalability, flexibility and high-density storage requirements.  
Seagate 1200 SSD drives are random access storage devices designed to support the Serial Attached SCSI Protocol as  
described in the ANSI specifications, this document, and the SAS Interface Manual (part number 100293071) which  
describes the general interface characteristics of this drive. Seagate 1200 SSD drives are classified as intelligent peripherals  
and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard. The SAS connectors, cables and electrical  
interface are compatible with Serial ATA (SATA), giving future users the choice of populating their systems with either SAS or  
SATA drives. This allows users to continue to leverage existing investment in SCSI while gaining a 12Gb/s serial data  
transfer rate.  
The Self-Encrypting Drive models indicated on the cover of this product manual have provisions for “Security of Data at Rest”  
based on the standards defined by the Trusted Computing Group (see www.trustedcomputinggroup.org).  
Note. Never disassemble and do not attempt to service items in the enclosure. The drive does not contain user-  
replaceable parts. Opening for any reason voids the drive warranty..

Formatted capacities  
Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time. Supported block  
sizes are 512, 520, 524, 528, 4096, 4160, 4192, and 4224. Users having the necessary equipment may modify the data  
block size before issuing a format command and obtain different formatted capacities than those listed.  
To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate  
recommends product planning in one of two modes:  
Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will  
meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with  
backward and forward compatibility from generation to generation. The current guaranteed operating points for this product  
are shown below. The Capacity stated is identical when the drive is formatted with or without PI enabled.

Programmable drive capacity  
Using the MODE SELECT command, the drive can change its capacity to something less than maximum. See the MODE  
SELECT (6) parameter list table in the SAS Interface Manual, part number 100293071. A value of zero in the Number of  
Blocks field indicates that the drive will not change the capacity it is currently formatted to have. A number other than zero  
and less than the maximum number of LBAs in the Number of Blocks field changes the total drive capacity to the value in the  
Number of Blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum capacity.

Factory-installed options  
OEMs may order the following items which are incorporated at the manufacturing facility during production or packaged  
before shipping. Some of the options available are (not an exhaustive list of possible options):  
• Other capacities can be ordered depending on LBA size requested and other factors.  
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit  
damage. Units shipped individually require additional protection as provided by the single unit shipping pack. Users plan-  
ning single unit distribution should specify this option.  
• The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM  
drive shipped, but extra copies may be ordered.  
3.8  
Thin Provisioning  
3.8.1 Logical Block Provisioning  
The drive is designed with a feature called Thin Provisioning. Thin Provisioning is a technique which does not require  
Logical Blocks to be associated to Physical Blocks on the storage medium until such a time as needed. The use of Thin  
Provisioning is a major factor in SSD products because it reduces the amount of wear leveling and garbage collection that  
must be performed. The result is an increase in the products endurance. For more details on Logical Block Provisioning and  
Thin Provisioning, Reference the SBC-3 document provided by the T-10 committee.  
3.8.2 Thin Provisioning capabilities  
The level of Thin Provisioning support may vary by product model. Devices that support Thin Provisioning are allowed to  
return a default data pattern for read requests made to Logical Blocks that have not been mapped to Physical Blocks by a  
previous WRITE command.  
In order to determine if Thin Provisioning is supported and what features of it are implemented requires the system to send a  
READ CAPACITY 16 (9Eh) command to the drive. Thin Provisioning and the READ CAPACITY 16 (9Eh) command is  
defined in the Seagate SCSI Command Reference 100293068.

operation, the device server sends user data with all bits set to zero to the data-in buffer. An LBPRZ bit set to zero indicates  
that, for an unmapped LBA specified by a read operation, the device server may send user data with all bits set to any value  
to the data-in buffer.  
3.8.3 UNMAP  
The UNMAP command requests that the device server break the association of a specific Logical Block address from a  
Physical Block, thereby freeing up the Physical Block from use and no longer requiring it to contain user data. An unmapped  
block will respond to a READ command with data that is determined by the setting of the LBPRZ bit in the READ CAPACITY  
parameter data.  
3.8.4 FORMAT UNIT command  
A device which supports Thin Provisioning will be capable of performing a SCSI FORMAT UNIT command which allocates  
Logical Blocks Addresses that are not linked to Physical Block Locations. A FORMAT command will cause all LBAs to  
become unmapped.  
3.8.5 Protection Information (PI) and Security (SED)  
The requirements in this section apply to any device which supports LBA unmapping.

In SCSI devices, umapped LBAs are defined as part of the Thin Provisioning model. Support of the Thin Provisioning model  
is indicated by the LBPME bit having a value of '1' in the READ CAPACITY (16) parameter data.  
When a region of LBA's are erased via cryptographic erase, as part of the erase, the drive shall unmap those LBAs.  
If the host attempts to access an unmapped or trimmed LBA, the drive shall return scrambled data. For a given LBA, the data  
shall be identical from access to access, until that LBA is either updated with actual data from the host or that LBA is  
cryptographically erased. The drive shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16)  
parameter data.  
If the host attempts to access an unmapped LBA on a drive that has been formatted with Protection Information (PI), the  
drive shall return scrambled PI data for that LBA. Depending on the value of the RDPROTECT field in the data-access  
command CDB, this may result in the drive returning a standard PI error to the host.  
If the host reduces the addressable capacity of the drive via a MODE SELECT command, the drive shall unmap or trim any  
LBA within the inaccessible region of the device.  
Additionally, an UNMAP command is not permitted on a locked band.

4.2.1 Response time  
Response time measurements are taken with nominal power at 25°C ambient temperature. The typical values in the table  
below are defined as follows:  
• Page-to-page response time is an average of all possible page-to-page accesses for a sequentially preconditioned  
drive.  
• Average response time is a true statistical random average of at least 5000 measurements of accesses between pro-  
grammable pages on a randomly preconditioned drive.

Peak performance is defined as the typical best case performance that the product will be able to achieve when  
the product is preconditioned as mentioned and host commands are aligned on 4KB boundaries.  
Sustained performance is defined as the worst case performance that the product will be able to achieve when the product is  
preconditioned as mentioned and host commands are aligned on 4KB boundaries. For models that support Lifetime  
Endurance Management, write values also take into account the worst case performance throttling that may occur to ensure  
the product meets specified reliability specifications.  
Due to the nature of Flash memory technologies there are many factors that can result in values different than those stated  
in this specification. Some discrepancies can be caused by bandwidth limitations in the host adapter, operating system, or  
driver limitations. It is not the intent of this manual to cover all possible causes of performance discrepancies.  
When evaluating performance of SSD devices, it is recommended to measure performance of the device in a method that  
resembles the targeted application using real world data and workloads. Test time should also be adequately large to ensure  
that sustainable metrics and measures are obtained.  
4.3  
Start/stop time  
The drive accepts the commands listed in the SAS Interface Manual less than 3 seconds after DC power has been applied.  
If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a START STOP UNIT  
command with the START bit equal to 0, the drive becomes ready for normal operations within 10 seconds (excluding the  
error recovery procedure).  
If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE  
SPINUP) primitive, the drive waits for a START STOP UNIT command with the START bit equal to 1. After receiving a  
START STOP UNIT command with the START bit equal to 1, the drive waits for a NOTIFY (ENABLE SPINUP) primitive.  
After receiving a NOTIFY (ENABLE SPINUP) primitive through either port, the drive becomes ready for normal operations  
within 10 seconds (excluding the error recovery procedure).  
If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does not receive a  
NOTIFY (ENABLE SPINUP) primitive within 5 seconds, the drive fails the START STOP UNIT command.  
The START STOP UNIT command may be used to command the drive to stop. Stop time is 3 seconds (maximum) from  
removal of DC power. SCSI stop time is 3 seconds. There is no power control switch on the drive.

4.4  
Cache control  
All default cache mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in  
4.4.1 Caching write data  
Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to be written to  
the medium is stored while the drive performs the WRITE command.  
If the number of write data logical blocks exceed the size of the segment being written into, when the end of the segment is  
reached, the data is written into the beginning of the same cache segment, overwriting the data that was written there at the  
beginning of the operation; however, the drive does not overwrite data that has not yet been written to the medium.  
If write caching is enabled (WCE=1), then the drive may return Good status on a WRITE command after the data has been  
transferred into the cache, but before the data has been written to the medium. If an error occurs while writing the data to the  
medium, and Good status has already been returned, a deferred error will be generated.  
Data that has not been written to the medium is protected by a back up power source which provides the ability of the data to  
be written to non-volatile medium in the event of an unexpected power loss.  
The SYNCHRONIZE CACHE command may be used to force the drive to write all cached write data to the medium. Upon  
completion of a SYNCHRONIZE CACHE command, all data received from previous WRITE commands will have been  
4.4.2 Prefetch operation  
If the Prefetch feature is enabled, data in contiguous logical blocks on the medium immediately beyond that which was  
requested by a Read command are retrieved and stored in the buffer for immediate transfer from the buffer to the host on  
subsequent Read commands that request those logical blocks (this is true even if cache operation is disabled). Though the  
prefetch operation uses the buffer as a cache, finding the requested data in the buffer is a prefetch hit, not a cache operation  
hit.  
To enable Prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0 enables prefetch.  
The drive does not use the Max Prefetch field (bytes 8 and 9) or the Prefetch Ceiling field (bytes 10 and 11).  
When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous blocks from the  
medium when it senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is  
not likely to occur.

1. Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated.  
2. As NAND Flash devices age with use, the capability of the media to retain a programmed value begins to deteriorate.  
This deterioration is affected by the number of times a particular memory cell is programmed and subsequently erased.  
When a device is new, it has a powered off data retention capability of up to several years. With use the retention capa-  
bility of the device is reduced. Temperature also has an effect on how long a Flash component can retain its programmed  
value with power removed. At high temperature the retention capabilities of the device are reduced. Data retention is  
not an issue with power applied to the SSD. The SSD drive contains firmware and hardware features that can monitor  
and refresh memory cells when power is applied.  
3. Endurance rating is the expected amount of host data that can be written by product when subjected to a specified work-  
load at a specified operating and storage temperature over the specified product life. For the specific workload to achieve  
12  
this level of endurance, please reference JEDEC Specification JESD218. TBW is defined as 1x10 Bytes.

5.1  
Error rates  
The error rates stated in this manual assume the following:  
• The drive is operated in accordance with this manual using DC power as defined in paragraph 6.3, "DC power require-  
• Errors caused by host system failures are excluded from error rate computations.  
• Assume random data.  
• Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry  
time.  
5.1.1 Unrecoverable Errors  
An unrecoverable data error is defined as a failure of the drive to recover data from the media. These errors occur due to  
read or write problems. Unrecoverable data errors are only detected during read operations, but not caused by the read. If an  
unrecoverable data error is detected, a MEDIUM ERROR (03h) in the Sense Key will be reported. Multiple unrecoverable  
data errors resulting from the same cause are treated as 1 error.  
5.1.2 Interface errors  
An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port  
connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC  
error.  
5.2  
Endurance Management  
Customer satisfaction with Solid State Drives can be directly related to the internal algorithms which an SSD uses to manage  
the limited number of Program-Erase (PE) cycles that NAND Flash can withstand. These algorithms consist of Wearleveling,  
Garbage Collection, Write Amplification, Unmap, Data Retention, Lifetime Endurance Management.  
5.2.1 Wear Leveling  
Wear Leveling is a technique used by the drive to ensure that all Flash cells are written to or exercised as evenly as possible  
to avoid any hot spots where some cells are used up faster than other locations. Wear Leveling is automatically managed by  
the drive and requires no user interaction. The Seagate algorithm is tuned to operate only when needed to ensure reliable  
product operation.  
5.2.2 Garbage Collection  
Garbage Collection is a technique used by the drive to consolidate valid user data into a common cell range freeing up  
unused or obsolete locations to be erased and used for future storage needs. Garbage Collection is automatically managed  
by the drive and requires no user interaction. The Seagate algorithm is tuned to operate only when needed to ensure reliable  
product operation.  
5.2.3 Write Amplification  
While Write Amplification is not an algorithm, it is a major characteristic of SSD's that must be accounted for by all the  
algorithms that the SSD implements. The Write Amplification Factor of an SSD is defined as the ratio of Host/User data  
requested to be written to the actual amount of data written by the SSD internal to account for the user data and the  
housekeeping activities such as Wear Leveling and Garbage Collection. The Write Amplification Factor of an SSD can also  
be directly affected by the characteristics of the host data being sent to the SSD to write. The best Write Amplification Factor  
is achieved for data that is written in sequential LBA's that are aligned on 4KB boundaries. The worst case Write  
Amplification Factor typically occurs for randomly written LBA's of transfer sizes that are less than 4KB and that originate on  
LBA's that are not on 4KB boundaries.  
5.2.4 UNMAP  
A new SCSI command has been added to the SSD as part of the Thin Provisioning feature set. Use of the UNMAP  
command reduces the Write Amplification Factor of the drive during housekeeping tasks such as Wear Leveling and  
Garbage Collection. This is accomplished because the drive does not need to retain data which has been classified by the  
host as obsolete.

5.2.5 Data Retention  
Data Retention is another major characteristic of SSD's that must be accounted for by all the algorithms that the SSD  
implements. While powered up, the Data Retention of SSD cells are monitored and rewritten if the cell levels decay to an  
unexpected level. Data Retention when the drive is powered off is affected by Program and Erase (PE) cycles and the  
temperature of the drive when stored.  
5.2.6 Lifetime Endurance Management (Available on select models)  
As stated in Section 5.2, an SSD has a limited number of Program and Erase (PE) cycles that are capable. In worse case  
applications, the write workload could be such that the drive experiences a high Write Amplification Factor that could lead to  
potential wear out prior to the drive achieving it's expected field life. Additionally, the Data Retention spec of the SSD needs  
to be considered to ensure the spec is met once the drive is worn out. Seagate has implemented a Lifetime Endurance  
Management technique which helps OEMS and user to avoid early wear out. By monitoring the write workload being sent to  
the drive, the drive can add additional response time to WRITE commands to provide a sustainable level of performance that  
is capable of being sustained for the life of the drive. Most users may never see this added response time in their  
applications.  
5.2.7 SSD Percentage Used Endurance Indicator  
An application can interrogate the drive through the host to determine an estimate of the percentage of device life that has  
been used. To accomplish this, issue a LOG SENSE command to log page 0x11. This allows applications to read the  
contents of the Percentage Used Endurance Indicator parameter code. The Percentage Used Endurance Indicator is defined  
in the T10 document SBC-3 available from the T10 committee.  
5.3  
Reliability and service  
Integrators can enhance the reliability of Seagate 1200 SSD drives by ensuring that the drive receives adequate cooling.  
5.3.1 Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF)  
The production drive shall achieve an AFR of 0.44% (MTBF of 2,000,000 hours) when operated in an environment that  
ensures the case temperatures do not exceed the values specified in Section 6.5. Operation at case temperatures outside  
the specifications in Section 6.5 may increase the product AFR (decrease the MTBF). The AFR (MTBF) is a population  
statistic not relevant to individual units.  
The AFR (MTBF) specification is based on the following assumptions for Enterprise Storage System environments:  
• 8760 power-on hours per year.  
• 250 average on/off cycles per year.  
• Operations at nominal voltages.  
• Systems will provide adequate cooling to ensure the case temperatures specified in Section 6.5 are not exceeded. Tem-  
peratures outside the specifications in Section 6.5 will increase the product AFR and decrease the MTBF.  
5.3.2 Preventive maintenance  
No routine scheduled preventive maintenance is required.  
5.3.3 Hot plugging the drive  
When a drive is powered on by switching the power or hot plugged, the drive runs a self test before attempting to  
communicate on its’ interfaces. When the self test completes successfully, the drive initiates a Link Reset starting with OOB.  
An attached device should respond to the link reset. If the link reset attempt fails, or any time the drive looses sync, the drive  
initiated link reset. The drive will initiate link reset once per second but alternates between port A and B. Therefore each port  
will attempt a link reset once per 2 seconds assuming both ports are out of sync.  
If the self-test fails, the drive does not respond to link reset on the failing port.  
Note. It is the responsibility of the systems integrator to assure that no temperature, energy, voltage hazard, or ESD  
potential hazard is presented during the hot connect/disconnect operation. Discharge the static electricity from  
the drive carrier prior to inserting it into the system.

5.3.4 S.M.A.R.T.  
S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize  
conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow administrators  
to back up the data before an actual failure occurs.  
Note. The drive’s firmware monitors specific attributes for degradation over time but can’t predict instantaneous drive  
failures.  
Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating performance of the  
drive and the thresholds are optimized to minimize “false” and “failed” predictions.  
Controlling S.M.A.R.T.  
The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Informational Exceptions Control  
mode page (1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feature. Setting the DEXCPT bit disables all  
S.M.A.R.T. functions. When enabled, S.M.A.R.T. collects on-line data as the drive performs normal read and write  
operations. When the PERF bit is set, the drive is considered to be in “On-line Mode Only” and will not perform off-line  
functions.  
An application can measure off-line attributes and force the drive to save the data by using the REZERO UNIT command.  
Forcing S.M.A.R.T. resets the timer so that the next scheduled interrupt is in one hour.  
An application can interrogate the drive through the host to determine the time remaining before the next scheduled  
measurement and data logging process occurs. To accomplish this, issue a LOG SENSE command to log page 0x3E. This  
allows applications to control when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the REZERO UNIT command  
resets the timer.  
Performance impact  
S.M.A.R.T. attribute data is saved to the media so that the events that caused a predictive failure can be recreated. The drive  
measures and saves parameters once every hour subject to an idle period on the drive interfaces. The process of measuring  
off-line attribute data and saving data to the media is interruptible. The maximum on-line only processing delay is  
summarized below  
Table 1:  
Maximum processing delay  
Fully-enabled delay  
DEXCPT = 0  
S.M.A.R.T. delay times  
75 ms  
Reporting control  
Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting  
method. For example, if the MRIE is set to one, the firmware will issue to the host an 01-5D00 sense code. The FRU field  
contains the type of predictive failure that occurred. The error code is preserved through bus resets and power cycles.  
Determining rate  
S.M.A.R.T. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors increases to  
an unacceptable level. To determine rate, error events are logged and compared to the number of total operations for a given  
attribute. The interval defines the number of operations over which to measure the rate. The counter that keeps track of the  
current number of operations is referred to as the Interval Counter.  
S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of  
errors for the current interval. This counter is referred to as the Failure Counter.  
Error rate is the number of errors per operation. The algorithm that S.M.A.R.T. uses to record rates of error is to set  
thresholds for the number of errors and appropriate interval. If the number of errors exceeds the threshold before the interval  
expires, the error rate is considered to be unacceptable. If the number of errors does not exceed the threshold before the  
interval expires, the error rate is considered to be acceptable. In either case, the interval and failure counters are reset and  
the process starts over.

Predictive failures  
S.M.A.R.T. signals predictive failures when the drive is performing unacceptably for a period of time. The firmware keeps a  
running count of the number of times the error rate for each attribute is unacceptable. To accomplish this, a counter is  
incremented each time the error rate is unacceptable and decremented (not to exceed zero) whenever the error rate is  
acceptable. If the counter continually increments such that it reaches the predictive threshold, a predictive failure is signaled.  
This counter is referred to as the Failure History Counter. There is a separate Failure History Counter for each attribute.  
5.3.5 Thermal monitor  
Seagate 1200 SSD drives implement a temperature warning system which:  
1. Signals the host if the temperature exceeds a value which would threaten the drive.  
2. Signals the host if the temperature exceeds a user-specified value. (i.e., the reference temperature value)  
3. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.  
A temperature sensor monitors the drive temperature and issues a warning over the interface when the temperature  
exceeds a set threshold. The temperature is measured at power-up and then at ten-minute intervals after power-up.  
The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the specified limit in  
compliance with the SCSI standard.  
This feature is controlled by the Enable Warning (EWasc) bit, and the reporting mechanism is controlled by the Method of  
Reporting Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page (1Ch).  
5.3.6 Drive Self Test (DST)  
Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST  
validates the functionality of the drive at a system level.  
There are two test coverage options implemented in DST:  
1. Extended test  
2. Short test  
The most thorough option is the extended test that performs various tests on the drive and scans every logical block address  
(LBA) of the drive. The short test is time-restricted and limited in length—it does not scan the entire media contents, but does  
some fundamental tests and scans portions of the media.  
If DST encounters an error during either of these tests, it reports a "diagnostic failed" condition. If the drive fails the test,  
remove it from service and return it to Seagate for service.  
5.3.6.1 DST failure definition  
The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a  
functional failure is encountered during DST. The drive parameters are not modified to test the drive more stringently, and the  
recovery capabilities are not reduced. All retries and recovery processes are enabled during the test. If data is recoverable,  
no failure condition will be reported regardless of the recovery processes required to recover the data.  
The following conditions are considered DST failure conditions:  
• Read error after recovery attempts are exhausted  
• Write error after recovery attempts are exhausted  
Recovered errors will not be reported as diagnostic failures.

5.3.6.2 Implementation  
This section provides all of the information necessary to implement the DST function on this drive.  
5.3.6.2.1  
State of the drive prior to testing  
The drive must be in a ready state before issuing the SEND DIAGNOSTIC command. There are multiple reasons why a  
drive may not be ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing  
a FORMAT UNIT, or another DST. It is the responsibility of the host application to determine the “not ready” cause.  
5.3.6.2.2  
Invoking DST  
To invoke DST, submit the SEND DIAGNOSTIC command with the appropriate Function Code (001b for the short test or  
010b for the extended test) in bytes 1, bits 5, 6, and 7.  
5.3.6.2.3  
Short and extended tests  
DST has two testing options:  
1. short  
2. extended  
These testing options are described in the following two subsections.  
Each test consists of two segments: an electrical test segment and a read/verify scan segment.  
Short test (Function Code: 001b)  
The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds.  
The short test does not scan the entire media contents, but does some fundamental tests and scans portions of the media. A  
complete read/verify scan is not performed and only factual failures will report a "diagnostic failed" condition. This option  
provides a quick confidence test of the drive.  
Extended test (Function Code: 010b)  
The objective of the extended test option is to empirically test critical drive components. The read operation tests the media  
contents. The integrity of the media is checked through a read/verify scan of the media.  
The anticipated length of the Extended test is reported through the Control Mode page.  
5.3.6.2.4  
Log page entries  
When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a  
new self-test parameter block at the beginning of the self-test results log parameter section of the log page. Existing data will  
be moved to make room for the new parameter block. The drive reports 20 parameter blocks in the log page. If there are  
more than 20 parameter blocks, the least recent parameter block will be deleted. The new parameter block will be initialized  
as follows:  
1. The Function Code field is set to the same value as sent in the DST command  
2. The Self-Test Results Value field is set to Fh  
3. The drive will store the log page to non-volatile memory  
After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its Self-Test Results  
Log page in non-volatile memory. The host may use LOG SENSE to read the results from up to the last 20 self-tests  
performed by the drive. The self-test results value is a 4-bit field that reports the results of the test. If the field is set to zero,  
the drive passed with no errors detected by the DST. If the field is not set to zero, the test failed for the reason reported in the  
field.  
The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The Sense key, ASC,  
ASCQ, and FRU are used to report the failure condition.

5.3.6.2.5 Abort  
There are several ways to abort a diagnostic. Applications can use a SCSI Bus Reset or a Bus Device Reset message to  
abort the diagnostic.  
Applications can abort a DST executing in background mode by using the abort code in the DST Function Code field. This  
will cause a 01 (self-test aborted by the application client) code to appear in the self-test results values log. All other abort  
mechanisms will be reported as a 02 (self-test routine was interrupted by a reset condition).  
5.3.7 Product warranty  
Warranty terms will vary based on type of warranty chosen: “Managed Life Warranty” or “Limited Warranty with Media  
Usage”. Consult the Seagate sales representative for warranty terms and conditions.  
Managed Life  
Limited Warranty with Media Usage  
This warranty is based on the shorter of term and endurance usage of the drive.  
Shipping  
When transporting or shipping a drive, use only a Seagate-approved container. Keep the original box. Seagate approved  
containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids  
the drive warranty.  
Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit. Contact the  
authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier  
experienced in handling computer equipment.  
Product repair and return information  
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction  
any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.  
Storage  
The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives should be  
stored in the original unopened Seagate shipping packaging when ever possible. Once the drive is removed from the  
Seagate original packaging the recommended maximum period between drive operation cycles is 30 days. During any  
storage period the drive non-operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic  
and electrical field specifications should be followed.

6.0 Physical/electrical specifications  
This section provides information relating to the physical and electrical characteristics of the drive.  
6.1  
Power specifications  
The 2.5” drive receives DC power (+5V and +12V) through the standard SAS interface.  
The 1.8" drive receives DC power (+3.3V and +5V) through the standard micro-SAS interface.  
6.1.1 Power consumption  
Power requirements for the drives are listed in the tables in Section 6.3. Typical power measurements are based on an  
average of drives tested, under nominal conditions, using the listed input voltage at 60°C ambient temperature.  
Measurements are made at 6Gb interface speeds. For 12Gb interface speed add 1W of total power to the values shown.  
• Startup power  
Startup power is measured from the time of power-on to the time that the drive reaches operating condition and can pro-  
cess media access commands.  
• Peak operating mode  
During peak operating mode, the drive is tested in various read and write access patterns to simulate the worst-case  
power consumption.  
• Idle mode power  
Idle mode power is measured with the drive powered up and ready for media access commands, with no media access  
commands having been received from the host.  
6.2  
AC power requirements  
None.

[1] Measured with average reading DC ammeter. Instantaneous +12V current peaks will exceed these values. Power sup-  
ply at nominal voltage. N (number of drives tested) = 6, 60 Degrees C ambient.  
[2] For +12 V, a 10% tolerance is allowed during initial start but must return to ±5% before reaching ready state. The ±5%  
must be maintained after the drive signifies that its power-up sequence has been completed and that the drive is able to  
accept selection by the host initiator.  
[3] This condition occurs after OOB and Speed Negotiation completes but before the drive has received the Notify Spinup  
primitive.  
[4] See paragraph 6.3.1, "Conducted noise immunity." Specified voltage tolerance includes ripple, noise, and transient  
response.  
General DC power requirement notes.  
1. Minimum current loading for each supply voltage is not less than 1.7% of the maximum operating current shown.  
2. The +3.3V, +5V and +12V supplies should employ separate ground returns.  
3. Where power is provided to multiple drives from a common supply, careful consideration for individual drive power  
requirements should be noted. Where multiple units are powered on simultaneously, the peak starting current must be  
available to each device.  
4. Parameters, other than start, are measured after a 10-minute warm up.

6.5  
Environmental limits  
Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part.  
Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C). Maximum wet bulb  
temperature is 84.2°F (29°C).  
Note. To maintain optimal performance drives should be run at nominal case temperatures.  
6.5.1 Temperature  
a. Operating  
The drive meets the operating specifications over a 41°F to 140°F (5°C to 60°C) drive case temperature range with a  
maximum temperature gradient of 36°F (20°C) per hour.  
The maximum allowable drive case temperature is 60°C.  
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal case tempera-  
ture. The rated MTBF is based upon a sustained case temperature of 122°F (50°C). Occasional excursions in operating  
temperature between the rated MTBF temperature and the maximum drive operating case temperature may occur with-  
out impact to the rated MTBF temperature. However continual or sustained operation at case temperatures beyond the  
rated MTBF temperature will degrade the drive MTBF and reduce product reliability.  
Air flow may be required to achieve consistent nominal case temperature values (see Section 6.5). To confirm that the  
required cooling is provided, place the drive in its final mechanical configuration, and perform random write/read opera-  
tions. After the temperatures stabilize, measure the case temperature of the drive. See Figure 14 and 15 for temperature  
checkpoint.  
b. Non-operating  
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification  
assumes that the drive is packaged in the shipping container designed by Seagate for use with drive.

6.5.2 Relative humidity  
The values below assume that no condensation on the drive occurs.  
a. Operating  
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.  
b. Non-operating  
5% to 95% non-condensing relative humidity.  
6.5.3 Effective altitude (sea level)  
a. Operating  
–1000 to +10,000 feet (–304.8 to +3048 meters)  
b. Non-operating  
–1000 to +40,000 feet (–304.8 to +12,192 meters)  
6.5.4 Shock and vibration  
Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an  
enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to the enclosure  
resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the  
enclosure to minimize drive movement.  
The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four  
6.5.4.1 Shock  
a. Operating—normal  
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding:  
• 1000 Gs at a maximum duration of 0.5ms (half sinewave)  
Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.  
Note. This specification does not cover connection issues that may result from testing at this level.  
b. Non-operating  
The limits of non-operating shock shall apply to all conditions of handling and transportation. This includes both isolated  
drives and integrated drives.  
The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device damage or per-  
formance degradation.  
• 1000 Gs at a maximum duration of 0.5ms (half sinewave)  
Shock may be applied in the X, Y, or Z axis.  
c. Packaged  
Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM standards. Vol-  
ume finished drives will be shipped from Seagate factories on pallets to minimize freight costs and ease material han-  
dling. Seagate finished drive bulk packs may be shipped individually. For less than full shipments, instructions are printed  
on the bulk pack carton for minimum drive quantities and proper drive placement.

11.08 GRMS  
Note. This specification does not cover connection issues that may result from testing at this level.  
b. Operating—abnormal  
Equipment as installed for normal operation shall not incur physical damage while subjected to periodic vibration:  
Vibration occurring at these levels may degrade operational performance during the abnormal vibration period. Specified  
operational performance will continue when normal operating vibration levels are resumed. This assumes system recov-  
ery routines are available.

6.5.5 Air cleanliness  
The drive is designed to operate in a typical office environment with minimal environmental control.  
6.5.6 Corrosive environment  
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial  
environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this  
accelerated testing cannot duplicate every potential application environment.  
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals  
as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold  
films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur  
is found to be the most damaging. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive  
compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing  
materials near circuitry with sulfide-free alternatives.  
Seagate recommends that data centers be kept clean by monitoring and controlling the dust and gaseous contamination.  
Gaseous contamination should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured on copper and silver  
coupons ), and dust contamination to ISO 14644-1 Class 8 standards, and MTBF rated conditions as defined in the  
Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF) section.

7.0 About FIPS  
The Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S. Government Computer Security Standard  
used to accredit cryptographic modules. It is titled 'Security Requirements for Cryptographic Modules (FIPS PUB 140-2)' and  
is issued by the National Institute of Standards and Technology (NIST).  
Purpose  
This standard specifies the security requirements that will be satisfied by a cryptographic module utilized within a security  
system protecting sensitive but unclassified information. The standard provides four increasing, qualitative levels of security:  
Level 1, Level 2, Level 3 and Level 4. These levels are intended to cover the wide range of potential applications and  
environments in which cryptographic modules may be employed.  
Validation Program  
Products that claim conformance to this standard are validated by the Cryptographic Module Validation Program (CMVP)  
which is a joint effort between National Institute of Standards and Technology (NIST) and the Communications Security  
Establishment (CSE) of the Government of Canada. Products validated as conforming to FIPS 140-2 are accepted by the  
Federal agencies of both countries for the protection of sensitive information (United States) or Designated Information  
(Canada).  
In the CMVP, vendors of cryptographic modules use independent, accredited testing laboratories to have their modules  
tested. National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratories perform cryptographic module

Security Level 2  
Security Level 2 enhances the physical security mechanisms of a Security Level 1 cryptographic module by adding the  
requirement for tamper-evidence, which includes the use of tamper-evident coatings or seals on removable covers of the  
module. Tamper-evident coatings or seals are placed on a cryptographic module so that the coating or seal must be broken  
to attain physical access to the critical security parameters (CSP) within the module. Tamper-evident seals (example shown  
in Figure 19, page 49) are placed on covers to protect against unauthorized physical access. In addition Security Level 2  
requires, at a minimum, role-based authentication in which a cryptographic module authenticates the authorization of an  
operator to assume a specific role and perform a corresponding set of services.

8.0 About self-encrypting drives  
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as  
“protection of data at rest.” These drives are compliant with the Trusted Computing Group (TCG) Enterprise Storage  
The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage  
and digital communications industry. The Seagate SED models comply with the standards published by the TCG.  
To use the security features in the drive, the host must be capable of constructing and issuing the following two SCSI  
commands:  
• SECURITY PROTOCOL OUT  
• SECURITY PROTOCOL IN  
These commands are used to convey the TCG protocol to and from the drive in the appropriate command payloads.  
8.1  
Data encryption  
Encrypting drives use one in-line encryption engine for each port, employing AES-256 data encryption in Cipher Block  
Chaining (CBC) mode to encrypt all data prior to being written on the media and to decrypt all data as it is read from the  
media. The encryption engines are always in operation and cannot be disabled.  
The 32-byte Data Encryption Key (DEK) is a random number which is generated by the drive, never leaves the drive, and is  
inaccessible to the host system. The DEK is itself encrypted when it is stored on the media and when it is in volatile  
temporary storage (DRAM) external to the encryption engine. A unique data encryption key is used for each of the drive's  
8.2  
Controlled access  
The drive has two security providers (SPs) called the "Admin SP" and the "Locking SP." These act as gatekeepers to the  
drive security services. Security-related commands will not be accepted unless they also supply the correct credentials to  
prove the requester is authorized to perform the command.  
8.2.1 Admin SP  
Admin SP is available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.  
8.2.2 Locking SP  
The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is  
available using the BandMasterX or EraseMaster passwords. Since the drive owner can define up to 16 data bands on the  
drive, each data band has its own password called BandMasterX where X is the number of the data band (0 through 15).  
8.2.3 Default password  
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value can only  
be read by the host electronically over the interface. After receipt of the drive, it is the responsibility of the owner to use the  
default MSID password as the authority to change all other passwords to unique owner-specified values.  
8.3  
Random number generator (RNG)  
The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to provide random  
numbers to the host for system use, including using these numbers as Authentication Keys (passwords) for the drive’s  
Admin and Locking SPs.

8.4  
Drive locking  
the individual bands.  
The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. In  
addition "ReadLockEnabled" and "WriteLockEnabled" must be set to true in the locking table in order for the bands  
"LockOnReset" setting of "PowerCycle" to actually lock access to the band when a "PowerCycle" event occurs. This  
scenario occurs if the drive is removed from its cabinet. The drive will not honor any data READ or WRITE requests until the  
bands have been unlocked. This prevents the user data from being accessed without the appropriate credentials when the  
drive has been removed from its cabinet and installed in another system.  
When the drive is shipped from the factory, the firmware download port is unlocked allowing the drive to accept any attempt  
to download new firmware. The drive owner must use the SID credential to lock the firmware download port before firmware  
updates will be rejected.  
8.5  
Data bands  
When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data  
Band) which comprises LBA 0 through LBA max. The host may allocate Band1 by specifying a start LBA and an LBA range.  
The real estate for this band is taken from the Global Band. An additional 14 Data Bands may be defined in a similar way  
(Band2 through Band15) but before these bands can be allocated LBA space, they must first be individually enabled using  
the EraseMaster password.  
Data bands cannot overlap but they can be sequential with one band ending at LBA (x) and the next beginning at LBA (x+1).  
Each data band has its own drive-generated encryption key and its own user-supplied password. The host may change the  
Encryption Key (see Section 8.6) or the password when required. The bands shall be aligned to 4KB LBA boundaries.  
8.6  
Cryptographic erase  
A significant feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change  
the data encryption key for a particular band. Once changed, the data is no longer recoverable since it was written with one  
key and will be read using a different key. Since the drive overwrites the old key with the new one, and keeps no history of  
key changes, the user data can never be recovered. This is tantamount to an instantaneous data erase and is very useful if  
the drive is to be scrapped or redispositioned.  
8.7  
Authenticated firmware download  
In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts  
download files which have been cryptographically signed by the appropriate Seagate Design Center.  
Three conditions must be met before the drive will allow the download operation:  
1. The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.  
2. The download file must be signed and authenticated.  
3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be appli-  
cable to the correct drive model, and have compatible revision and customer status.

Power requirements  
The standard drive models and the SED drive models have identical hardware, however the security and encryption portion  
of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V  
supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on  
8.9  
Supported commands  
The SED models support the following two commands in addition to the commands supported by the standard (non-SED)  
models as listed in Table 15:  
• SECURITY PROTOCOL OUT (B5h)  
• SECURITY PROTOCOL IN (A2h)  
8.10  
Sanitize - Cryptographic Erase  
This command cryptographically erases all user data on the drive by destroying the current data encryption key and  
replacing it with a new data encryption key randomly generated by the drive. Sanitize CRYPTOGRAPHIC ERASE is a SCSI  
CDB Op code 48h and selecting the service action code 3 (CRYPTOGRAPHIC ERASE).  
8.11  
RevertSP  
SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents of all  
SPs (Security Providers) on the device to their original factory state. In order to execute the RevertSP method the unique  
PSID (Physical Secure ID) printed on the drive label must be provided. PSID is not electronically accessible and can only be  
manually read from the drive label or scanned in via the 2D barcode.

9.0 Defect and error management  
Seagate continues to use innovative technologies to manage defects and errors. These technologies are designed to  
increase data integrity, perform drive self-maintenance, and validate proper drive operation.  
SCSI defect and error management involves drive internal defect/error management and SAS system error considerations  
(errors in communications between the initiator and the drive). In addition, Seagate provides the following technologies used  
to increase data integrity and drive reliability:  
• Auto-Reallocation (see Section 9.4)  
The read error rates and specified storage capacities are not dependent on host (initiator) defect management routines.  
9.1  
Drive internal defects/errors  
During the initial drive manufacturing test operation at the factory, media defects are identified, tagged as being unusable,  
and their locations recorded on the drive primary defects list (referred to as the “P’ list). At factory format time, these known  
defects are also deallocated, that is, marked as retired and the location listed in the defects reallocation table. The “P” list is  
not altered after factory formatting. Locations of defects found and reallocated during error recovery procedures after drive  
shipment are listed in the “G” list (defects growth list). The “P” and “G” lists may be referenced by the initiator using the READ  
DEFECT DATA command.  
Details of the SCSI commands supported by the drive are described in the SAS Interface Manual. Also, more information on  
the drive Error Recovery philosophy is presented in the SAS Interface Manual.  
The drive uses a vendor unique format to report defects via the READ DEFECT DATA command pending T10  
standardization of a format for Solid State Devices. This format defect type is defined as 110b in the SCSI FORMAT UNIT  
command. The definition of the 110b format is defined in the following table.

The VENDOR UNIQUE field may contain vendor unique information.  
9.2  
Drive error recovery procedures  
When an error occurs during drive operation, the drive performs error recovery procedures to attempt to recover the data.  
The error recovery procedures used are not user changeable.  
9.3  
SAS system errors  
Information on the reporting of operational errors across the interface is given in the SAS Interface Manual. The SSP  
Response returns information to the host about numerous kinds of errors. The Receive Diagnostic Results reports the results  
of diagnostic operations performed by the drive.  
Status returned by the drive to the initiator is described in the SAS Interface Manual. Status reporting plays a role in systems  
error management and its use in that respect is described in sections where the various commands are discussed.

9.4  
Auto-Reallocation  
Auto-Reallocation allows the drive to reallocate unreadable locations on a subsequent write command if the recovery  
process deems the location to be defective. The drive performs auto-reallocation on every WRITE command. With each  
write to a Logical LBA, the drive writes the data to a different physical media location. Physical locations that return  
unrecoverable errors are retired during future WRITE attempts and associated recovery process.  
This is in contrast to the system having to use the REASSIGN BLOCKS command to reassign a location that was  
unreadable and then generate a WRITE command to rewrite the data. This operation requires that AWRE and ARRE are  
enabled—this is the default setting from the Seagate factory.  
9.5  
Protection Information (PI)  
Protection Information is intended as a standardized approach to system level LRC traditionally provided by systems using  
520 byte formatted LBAs. Drives formatted with PI information provide the same, common LBA count (i.e. same capacity  
point) as non-PI formatted drives. Sequential performance of a PI drive will be reduced by approximately 1.56% due to the  
extra overhead of PI being transferred from the media that is not calculated as part of the data transferred to the host. To  
determine the full transfer rate of a PI drive, transfers should be calculated by adding the 8 extra bytes of PI to the transferred  
LBA length, i.e. 512 + 8 = 520. PI formatted drives are physically formatted to 520 byte LBA’s that store 512 bytes of  
customer data with 8 bytes of Protection Information appended to it. The advantage of PI is that the Protection Information  
bits can be managed at the HBA and HBA driver level. Allowing a system that typically does not support 520 LBA formats to  
integrate this level of protection.  
Protection Information is valid with any supported LBA size. 512 LBA size is used here as common example.  
9.5.1 Levels of PI  
There are 4 types of Protection Information.  
Type 0 - Describes a drive that is not formatted with PI information bytes. This allows for legacy support in non-PI systems.  
Type 1 - Provides support of PI protection using 10 and 16 byte commands. The RDPROTECT and WRTPROTECT bits  
allow for checking control through the CDB. Eight bytes of Protection Information are transmitted at LBA boundaries across  
the interface if RDPROTECT and WRTPROTECT bits are nonzero values. Type 1 does not allow the use of 32 byte  
commands.  
Type 2 - Provides checking control and additional expected fields within the 32 byte CDBs. Eight bytes of Protection  
Information are transmitted at LBA boundaries across the interface if RDPROTECT and WRTPROTECT bits are nonzero  
values. Type 2 does allow the use of 10 and 16 byte commands with zero values in the RDPROTECT and WRTPROTECT  
fields. The drive will generate 8 bytes of Protection Information (e.g. 0xFFFFFFFF) to be stored on the media, but the 8 bytes  
will not be transferred to the host during a READ command.  
Type 3 - Seagate products do not support Type 3.  
9.5.2 Setting and determining the current Type Level  
A drive is initialized to a type of PI by using the FORMAT UNIT command on a PI capable drive. Once a drive is formatted to  
a PI Type, it may be queried by a READ CAPACITY (16) command to report the PI type which it is currently formatted to. A  
drive can only be formatted to a single PI Type. It can be changed at anytime to a new Type but requires a FORMAT UNIT  
command which destroys all existing data on the drive. No other vehicle for changing the PI type is provided by the T10  
SBC3 specification.  
Type 1 PI FORMAT UNIT CDB command: 04 90 00 00 00 00, parameter data: 00 A0 00 00  
Type 2 PI FORMAT UNIT CDB command: 04 D0 00 00 00 00, parameter data: 00 A0 00 00  
9.5.3 Identifying a Protection Information drive  
The Standard INQUIRY data provides a bit to indicate if PI is support by the drive. Vital Product Descriptor (VPD) page 0x86  
provides bits to indicate the PI Types supported and which PI fields the drive supports checking.  
Note. For further details with respect to PI, please refer to SCSI Block Commands - 3 (SBC-3) Draft Standard docu-  
mentation.

10.0 Installation  
Seagate 1200 SSD drive installation is a plug-and-play process. There are no jumpers on the drive.  
SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to  
accommodate the drive. In such systems, the host system typically provides a carrier or tray into which the drive must be  
mounted. Mount the drive to the carrier or tray provided by the host system using four M3 x 0.5 metric screws. When  
tightening the screws, use a maximum torque of 4.5 in-lb +/- 0.45 in-lb. Do not over-tighten or force the screws. The drive  
can be mounted in any orientation.  
Note. SAS drives are designed to be attached to the host system without I/O or power cables. If the intent is to use the  
drive in a non-backplane host system, connecting the drive using high-quality cables is acceptable as long as the  
I/O cable length does not exceed 10 meters (32.8 feet).  
Slide the carrier or tray into the appropriate bay in the host system using the instructions provided by the host system. This  
connects the drive directly to the system’s SAS connector. The SAS connector is normally located on a SAS backpanel. See  
Power is supplied through the SAS connector.  
The drive is shipped from the factory low-level formatted in 512-byte logical blocks. Reformatting the drive is only required if  
the application requires a different logical block size.

10.1  
Drive orientation  
The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the  
drive in horizontal (level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.  
10.2  
Cooling  
Cabinet cooling must be designed by the customer so that the temperature of the drive will not exceed temperature  
The rack, cabinet, or drawer environment for the drive must provide heat removal from the assembly. The system designer  
should confirm that adequate heat removal is provided using the temperature measurement guidelines described in Section  
the drive should be oriented, or air flow directed, so that the least amount of air flow resistance is created while providing air  
flow. Also, the shortest possible path between the air inlet and exit should be chosen to minimize the travel length of air  
heated by the drive and other heat sources within the rack, cabinet, or drawer environment.  
If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 21. The air-flow patterns are  
created by one or more fans, either forcing or drawing air as shown in the illustrations. Conduction, convection, or other

10.3  
Drive mounting  
Mount the drive using the bottom or side mounting holes. If mounting the drive using the bottom holes, ensure not to  
physically distort the drive by attempting to mount it on a stiff, non-flat surface.  
The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). The following equation and paragraph define the allowable  
mounting surface stiffness:  
K x X = F < 15lb = 67N  
where K is the mounting surface stiffness (units in lb/in or N/mm) and X is the out-of-plane surface distortion (units in inches  
or millimeters). The out-of-plane distortion (X) is determined by defining a plane with three of the four mounting points fixed  
and evaluating the out-of-plane deflection of the fourth mounting point when a known force (F) is applied to the fourth point.  
10.4  
Grounding  
Signal ground (PCBA) and case ground are connected together in the drive and cannot be separated by the user. The  
equipment in which the drive is mounted is connected directly to the drive with no electrically isolating shock mounts. If it is  
desired for the system chassis to not be connected to the drive ground, the systems integrator or user must provide a  
nonconductive (electrically isolating) method of mounting the drive in the host equipment.  
Increased radiated emissions may result if designers do not provide the maximum surface area ground connection between  
system ground and drive ground. This is the system designer’s and integrator’s responsibility.

Dual port support  
Seagate 1200 SSD SAS drives have two independent ports. These ports may be connected in the same or different SCSI  
domains. Each drive port has a unique SAS address.  
The two ports have the capability of independent port clocking (e.g. both ports can run at 12Gb/s or the first port can run at  
12Gb/s while the second port runs at 6Gb/s.) The supported link rates are 1.5, 3.0, 6.0 or 12.0 Gb/s.  
Subject to buffer availability, the Seagate 1200 SSD drives support:  
• Concurrent port transfers—The drive supports receiving COMMAND, TASK management transfers on both ports at the  
same time.  
• Full duplex—The drive supports sending XFER_RDY, DATA and RESPONSE transfers while receiving frames on both  
ports.

11.3.2 MODE SENSE data  
The MODE SENSE command provides a way for the drive to report its operating parameters to the initiator. The drive  
maintains four sets of mode parameters:  
1. Default values  
Default values are hard-coded in the drive firmware stored in flash E-PROM (nonvolatile memory) on the drive’s PCB.  
These default values can be changed only by downloading a complete set of new firmware into the flash E-PROM. An  
initiator can request and receive from the drive a list of default values and use those in a MODE SELECT command to  
set up new current and saved values, where the values are changeable.  
2. Saved values  
Saved values are stored on the drive’s media using a MODE SELECT command. Only parameter values that are  
allowed to be changed can be changed by this method. Parameters in the saved values list that are not changeable by  
the MODE SELECT command get their values from default values storage.  
When power is applied to the drive, it takes saved values from the media and stores them as current values in volatile  
memory. It is not possible to change the current values (or the saved values) with a MODE SELECT command before  
the drive is “ready.” An attempt to do so results in a “Check Condition” status.  
On drives requiring unique saved values, the required unique saved values are stored into the saved values storage  
location on the media prior to shipping the drive. Some drives may have unique firmware with unique default values also.  
On standard OEM drives, the saved values are taken from the default values list and stored into the saved values stor-  
age location on the media prior to shipping.  
3. Current values  
Current values are volatile values being used by the drive to control its operation. A MODE SELECT command can be  
used to change the values identified as changeable values. Originally, current values are installed from saved or default  
values after a power on reset, hard reset, or Bus Device Reset message.  
4. Changeable values  
Changeable values form a bit mask, stored in nonvolatile memory, that dictates which of the current values and saved  
values can be changed by a MODE SELECT command. A one (1) indicates the value can be changed. A zero (0) indi-  
cates the value is not changeable. For example, in Table 18, refer to Mode page 81, in the row entitled “CHG.” These are  
hex numbers representing the changeable values for Mode page 81. Note in columns 5 and 6 (bytes 04 and 05), there is  
00h which indicates that in bytes 04 and 05 none of the bits are changeable. Note also that bytes 06, 07, 09, 10, and 11  
are not changeable, because those fields are all zeros. In byte 02, hex value FF equates to the binary pattern 11111111.  
If there is a zero in any bit position in the field, it means that bit is not changeable. Since all of the bits in byte 02 are  
ones, all of these bits are changeable.  
The changeable values list can only be changed by downloading new firmware.  
Note. Because there are often several different versions of drive control firmware in the total population of drives in the  
field, the MODE SENSE values given in the following tables may not exactly match those of some drives.  
The following tables list the values of the data bytes returned by the drive in response to the MODE SENSE command pages  
for SCSI implementation (see the SAS Interface Manual).  
DEF = Default value. Standard OEM drives are shipped configured this way.  
CHG = Changeable bits; indicates if default value is changeable.

11.4.7 Power  
The drive receives power (+3.3 volts, +5 volts and +12 volts) through the SAS device connector.  
Three +12 volt pins provide power to the drive, 2 short and 1 long. The current return for the +12 volt power supply is through  
the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins.  
Three +5 volt pins provide power to the drive, 2 short and 1 long. The current return for the +5 volt power supply is through  
the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins.  
Two +3.3 volt pins provide power to the drive, 1 short and 1 long. The current return for the +3.3 volt power supply is through  
the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins.  
Current to the drive through the long power pins may be limited by the system to reduce inrush current to the drive during hot  
plugging.

The Ready LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +3.3 volt  
supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. See  
Table 26 for the output characteristics of the LED drive signals.

SAS-3 Specification compliance  
Seagate SAS-3 drives are entirely compatible with the SAS-3 Specification (T10/2212-D).  
The most important characteristic of the SAS-3 drive at 6Gb/s is that the receiver is capable of adapting the equalizer to  
optimize the receive margins. The SAS-3 drive has two types of equalizers:  
1. A Decision Feedback Equalizer (DFE) which utilizes the standard SAS-3 training pattern transmitted during the SNW-3  
training gap. The DFE circuit can derive an optimal equalization characteristic to compensate for many of the receive  
losses in the system.  
2. A Feed Forward Equalizer (FFE) optimized to provide balanced receive margins over a range of channels bounded by  
the best and worst case channels as defined by the relevant ANSI standard.
