Travelstar 5K750 is a 5400 RPM, 375GB/platter, 2.5-inch hard drive with capacities of 500GB, 640GB and 750GB. This standard 9.5mm, two-disk design, intended for use in notebook PCs, external storage, gaming consoles and other mobile applications, is HGST's first to leverage Advanced Format. Advanced Format increases the physical sector size on hard drives from 512 bytes to 4096 (4K) bytes, which increases drive capacities and improves error correction capabilities. The Travelstar 5K750 allows manufacturers to deliver high capacity, power efficient systems. Manufacturers can consult the HGST Advanced Format Technology Brief for more information on using these hard drives. The 5K750 continues to demonstrate HGST's ecological leadership, with its halogen free and low power products, and carries the EcoTrac classification. Travelstar 5K750 delivers the balance of capacity, ruggedness and low power to meet the needs of consumers and commercial users in an eco-friendly design. Travelstar 5K750 is the fifth generation self encrypting drive (SED) to feature HGST's Bulk Data Encryption. The SED encrypts data using protected keys in real time, 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. HGST provides enhanced availability models that allow the Travelstar 5K750 to deliver 24x7 access to data for data intensive applications requiring round-the-clock operation. The 5K750 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.
