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 ofalways-on”  
applications in lower-transaction environments.
