Quiet, rugged, low-power HDD solution for mobile applications
Travelstar™ Z5K320 is a 7mm, 5400 rPM 2.5-inch hard drive with capacities ranging 
from 160GB to 320GB. The 320GB per platter one-disk models are designed as a direct 
replacement for standard 9.5mm hdds, for use in notebook PCs, external storage and 
gaming consoles. The Z5K320 also accommodates new thinner and more robust device 
designs. These models deliver best-of-breed acoustics for near silent operation. along with 
continued focus on superior shock protection and low-power consumption, hitachi leads 
on the environmental front with its halogen-free production. hitachi offers optional hard-
drive-level encryption for increased data security and models with enhanced availability to 
deliver high-capacity storage for non-stop environments. Travelstar Z5K320 delivers the right 
balance of capacity, power-management and design flexibility to meet the needs of mobile 
applications in an eco-friendly footprint.  
Data security option
Travelstar Z5K320 is the fourth generation to feature optional Bulk data encryption (Bde) for 
hard-drive-level data security. With Bde, the data is scrambled using a key as it is written to 
the disk, then descrambled with the key as it is retrieved, giving users the highest level of 
data protection available. it also speeds and simplifies 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. For information about the self-encrypting drives 
designed to the Trusted Computing Group (TCG) Opal storage security specification, please 
contact your hitachi representative.
Enhanced Availability (EA)—for 24x7 access to data
hitachi provides enhanced-availability models of the Travelstar Z5K320 that deliver 24x7 
access to information for data-intensive applications requiring round-the-clock operation. The 
new thinner profile allows for additional cooling, especially important in dense blade server 
designs. The Z5K320 provides high capacity, performance and durability on a proven platform 
for quality and reliability.  ea models support the stringent demands of “always-on” applications 
in lower-transaction environments.
