Reliable, high-capacity storage for mobile applications
Travelstar™ 5K500.B, a 5400 RPM, 250GB/platter, 2.5-inch hard drive with capacities ranging 
from 120GB to 500GB, is designed for use in notebook PCs, external storage, gaming 
consoles and other mobile applications. The 5K500.B demonstrates Hitachi’s ecological 
leadership with its halogen-free production and focus on low power consumption, and carries 
the EcoTrac classification. The 5K500.B elevates hard drive reliability with the industry’s first 
Iterative Detection Read Channel for improved signal processing. Hitachi offers optional hard-
drive-level encryption for increased data security and enhanced availability models to deliver 
high-capacity storage for non-stop environments. Travelstar 5K500.B delivers the balance of 
capacity, ruggedness and low-power to meet the needs of consumers and commercial users 
in an eco-friendly footprint.
Encryption option
Travelstar 5K500.B features optional Bulk Data Encryption (BDE) for hard-drive-level data 
security. Hitachi is working with the Trusted Computing Group (TCG) to ensure that our 
new products conform to the Storage Security specification that 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 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 provides enhanced availability models that allow the Travelstar 5K500.B to deliver 24x7 
access to data for data-intensive applications requiring round-the-clock operation. The 5K500.B 
provides high capacity, durability and low power utilization on a proven platform for quality 
and reliability. EA models support the stringent demands of “always-on” applications in lower-
transaction environments.
