Reliable, high-capacity storage for mobile applications  
Travelstar5K320 is a 5400 RPM 2.5-inch hard drive with capacities ranging from 80GB to  
320GB. The 160GB per platter one- and two-disk models are designed for use in notebook  
PCs, set-top boxes, gaming consoles and other mobile applications. The 5K320 raises the  
standard for hard drive reliability with design enhancements that include altitude-sensing  
Thermal Fly-height Control (TFC), an improved actuator latch and fourth generation  
perpendicular magnetic recording (PMR) head technology. Along with the attention to  
ruggedness, Hitachi continues to deliver excellent performance and low-power leadership.  
Designed to support the multi-tasking needs of consumers and commercial users balancing  
mobile computing and movies, music, photos and games on the go, Travelstar 5K320  
delivers the right capacity and performance options to meet the needs of IT and consumer  
electronics manufacturers. Hitachi offers optional hard-drive-level encryption for users looking  
for increased data security and models with enhanced availability to deliver high-capacity  
storage for non-stop environments.  
Data security option  
Travelstar 5K320 features optional Bulk Data Encryption (BDE) with a SATA 1.5Gb/s interface  
for hard-drive-level data security. The data is scrambled using a key as it is written to the disk  
then descrambled with the key as it’s retrieved, giving users a higher level of data protection  
than traditional password-based security previously available. Another benet is that it speeds  
and simplies the drive re-deployment process. By deleting the encryption key, the data on the  
drive is rendered unreadable, thereby eliminating the need for time-consuming data-overwrite.  
320, 250, 160, 120 and  
80 GB | 5400 RPM  
SATA 3Gb/s and 1.5Gb/s  
Enhanced Availability (EA)—for 24x7 access to data  
Hitachi provides enhanced-availability models that employ specic microcode to allow the  
Travelstar 5K320 to deliver 24x7 access to data. These models broaden the product line  
to make it more suitable for data-intensive applications requiring round-the-clock operation.  
The 5K320 provides high capacity, performance, durability and efcient power utilization  
on a proven platform for quality and reliability. EA models support the stringent demands  
of “always-on” applications in lower-transaction environments.
