Leadership performance  
Ultrastar™ C10K900 is a 2.5-inch 10,000 RPM hard drive that leads the industry with 18%  
faster sequential and up to 17% random performance than the nearest competitor. The high-  
performance SAS 6Gb/s interface delivers data reliability, availability and scalability and is the  
only small form factor SAS drive in the industry to pack a 64MB cache buffer for optimized  
read/write response time.  
> High performance computing and other  
24x7 applications  
> Cloud computing  
Best-in-class power performance  
Power management innovations designed into the Ultrastar C10K900 enable industry-leading  
power efficiency, up to 28% better than competing drives, and translate into reduced power  
requirements and lower cooling costs. Hitachi Advanced Power Management technology,  
with multi-state idle modes, maintains compatibility with the INCITS T10 Technical Committee  
standards direction and can be pre-programmed or manually initiated in the system. Ultrastar  
C10K900 continues the Hitachi tradition of environmental leadership with its halogen-reduced  
components and focus on low power consumption, and carries the Hitachi EcoTrac classification.

2.5-inch SFF SAS 6Gb/s  
Ultrastar C10K900 delivers capacity parity with 3.5-inch 10K drives, providing a massive  
900GB of storage space and enabling lower total cost of ownership for many Enterprise  
environments, especially networked storage arrays. When faced with space and power limitations,  
the Ultrastar C10K900 is an efficient solution for online transaction processing, intensive  
data analysis and multi-user applications. Some models of the C10K900 also offer Bulk Data  
Encryption for hard-drive-level data security. These self-encrypting models are designed to  
the Trusted Computing Group’s Enterprise A Security Subsystem Class encryption specification  
and allow customers to reduce costs associated with drive retirement and extend drive life by  
enabling swift and secure repurposing of drives.
