High-performance, quiet HDD solution for mobileapplications
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 anddelivers 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, hitachi delivers best-of-breed acoustics. hitachi offers optional hard-drive-level
encryption for increased data security and models with enhanced availability to deliver highperformance 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

320, 250 and 160GB
7200 rPM | saTa 3Gb/s

Travelstar Z7K320 is the fourth generation to feature optional Bulk data encryption (Bde) for
hard-drive-level data security. hitachi has designed these self-encrypting drivesto the Trusted
Computing Group (TCG) Opal storage security specification, which is expected to become
an industry standard. 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 theencryption
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 of the Travelstar Z7K320 that deliver 24x7
access to information for data-intensive applications requiring round-the-clock operation.
