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 HGST'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. HGST 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. 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
HGST 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.
