Rugged, 500GB Single-disk HDD Solution for Slim Mobile Applications
Travelstar® Z5K500 is the second generation 7mm, 5400 RPM 2.5-inch hard drive from HGST, with capacities ranging from 250GB to 500GB and the second generation Advanced Format drive. Advanced Format increases the physical sector size on HDDs from 512 bytes to 4,096 (4K) bytes, which improves drive capacities and error correction capabilities. 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 Z5K500 carries the EcoTrac classification due to its low power consumption and eco-friendly, halogen-free production. Travelstar Z5K500 delivers the right balance of capacity, power-management and design flexibility to meet the needs of mobile applications.
Data Security Option
Travelstar Z5K500 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 Z5K500 that deliver 24x7 access to information for data-intensive applications requiring round-the-clock operation. The new thinner profile allows for additional cooling, especially important in dense blade server designs. The Z5K500 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.
