Highlights  
High-Performance, Quiet HDD Solution For Mobile Applications  
Travelstar™ Z7K320 is the industry’s first 7200 RPM, 7mm, 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 compact systems. The Z7K320 offers design flexibility to accommodate new thinner  
and more robust devices/systems and delivers up to 18% better application performance  
than 5400 RPM models of the same capacity. Along with continued focus on superior shock  
protection and low power consumption, HGST delivers best-of-breed acoustics. HGST offers  
optional hard-drive-level encryption for increased data security and models with enhanced  
availability to deliver high-performance storage for non-stop environments. Travelstar  
Z7K320 provides the right balance of performance and capacity to meet the multi-tasking  
needs of commercial and consumer users on the go.

Data Security Option  
Travelstar Z7K320 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 HGST representative.  
Enhanced Availability (EA)—for 24x7 Access to Data  
HGST provides enhanced-availability models of the Travelstar Z7K320 that deliver 24x7  
access to information for data-intensive applications requiring round-the-clock operation.  
The new, slimmer profile provides for additional cooling, especially important in dense blade  
server designs. The Z7K320 provides high capacity, performance and durability on a proven  
platform for quality and reliability. EA models support the stringent demands ofalways-on”  
applications in lower-transaction environments.
