High-Performance, Single-Disk 500GB HDD for Mobile Applications

Travelstar™ Z7K500 is the second generation 7mm, 7200 RPM 2.5-inch hard drive from

HGST, with capacities ranging from 250GB to 500GB leveraging Advanced Format, which

increases the physical sector size from 512 bytes to 4,096 (4K) bytes to improve drive

capacities and error correction capabilities. Travelstar Z7K500 is the first 2.5-inch HDD with

a 6Gb/s SATA interface and 32MB of cache and delivers the highest 7200 RPM performance

in PCMark Vantage testing. The 500GB per platter, one-disk models are designed as a direct

replacement for standard 9.5mm HDDs, for use in notebook PCs, external storage and

gaming consoles, as well as new, thinner and more robust device designs. The Z7K500 carries

the EcoTrac classification due to its low power consumption and eco-friendly, halogen-free

production. Travelstar Z7K500 balances speed, power-efficiency and design flexibility to

meet the needs of mobile applications.

Data Security Option

Travelstar Z7K500 is the sixth generation self-encrypting drive (SED) to feature HGST’s

Bulk Data Encryption (BDE). The SED model encrypts data in real time using protected

keys, providing users the highest level of data protection available. It also speeds and

simplifies drive re-purposing. By deleting the encryption key, the data on the drive is

rendered unreadable, thereby eliminating the need for time-consuming data-overwrite. For

information about the SED models designed to the Trusted Computing Group (TCG) Opal

Storage Security specification, please contact your HGST representative.

Enhanced Availability (EA)—for 24x7 Access to Data

HGST provides enhanced availability models of the Travelstar Z7K500 that allow 24x7 access

to data to support applications that require round-the-clock operation. The new thinner

profile allows for additional cooling, especially important in dense blade server designs.

The Z7K500 provides high capacity, durability and quiet acoustics on a proven platform

for quality and reliability. EA models support the stringent demands of “always-on”

applications in lower-transaction environments.
