High-performance mobile storage without sacrificing capacity or power
Travelstar™ 7K320 is the industry’s only fourth-generation 7200 RPM 2.5-inch hard drive with
capacities ranging from 80GB to 320GB, equivalent to Hitachi 5400 RPM products. The 160GB
per platter one- and two-disk models deliver 60% higher capacity and 12% better application
performance than its predecessor. Hitachi provides best-of-breed power and operating shock
in Travelstar 7K320 by matching its 5400 RPM models. Designed to support the high-
performance needs of multi-tasking commercial users and consumers on-the-go, Travelstar
7K320 offers speed without sacricing battery life, capacity or audio quality. 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 7K320 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. Another benet is that it speeds and simpli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 offers enhanced-availability models that employ specic microcode to allow the
Travelstar 7K320 to provide 24x7 access to data. These models broaden the product line to
make it more suitable for data-intensive applications requiring around-the-clock operation.
The 7K320 provides high performance, capacity, durability and power utilization on a proven
platform for quality and reliability. EA models support the stringent demands of “always-on”
applications in lower-transaction environments.
