Reliable, high-capacity storage for mobile applications
Travelstar
 5K320 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 benefi t is that it speeds 
and simplifi es 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.
Enhanced Availability (EA)—for 24x7 access to data
Hitachi provides enhanced-availability models that employ specifi c 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 effi cient power utilization 
on a proven platform for quality and reliability. EA models support the stringent demands 
of “always-on” applications in lower-transaction environments.
