Travelstar Z7K500
2.5-Inch Mobile 7200 RPM 7mm Hard Disk Drives

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 continues to demonstrate HGST’s ecological leadership with its low power consumption and 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.
