High-performance mobile storage without sacrificing capacity or power
Travelstar™ 7K500 is the industry’s only fifth-generation 7200 RPM 2.5-inch hard drive with 
capacities ranging from 120GB to 500GB, matching Hitachi 5400 RPM capacities. The 250GB 
per platter one- and two-disk models deliver up to 56% higher capacity and 16% better 
application performance than its predecessor. Hitachi provides best-of-breed operating shock 
and outstanding power management in Travelstar 7K500 for sturdy unplugged notebook 
performance. With its halogen-free production and low power consumption, the 7K500 carries 
the Hitachi EcoTrac classification. Designed to support the high-performance needs of multi-
tasking commercial users and consumers on-the-go, Travelstar 7K500 offers speed without 
sacrificing 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.  
Encryption and TCG Opal specification
Travelstar 7K500 features optional Bulk Data Encryption (BDE), now with a 3Gb/s SATA 
interface, for hard-drive-level data security. A new encryption model of the 7K500 conforms 
to the Trusted Computing Group Opal specification, supporting industry standardization. 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. 
It also speeds and simplifies the drive re-deployment process. By deleting the encryption key, 
the data 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 specific microcode to allow the  
Travelstar 7K500 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 7K500 provides high performance, capacity, durability and efficient power utilization 
on a proven platform for quality and reliability. EA models support the stringent demands of 
“always-on” applications in lower-transaction environments.
