Hitachi Travelstar 7K750 HTS727550A9E364 / 0J12281 500GB 7.2K 2.5 inch Laptop SATA Hard Drive - New Pull

High-Capacity Storage Paves the Way for New Mobile Platforms

Travelstar™ 7K750 is a 7200RPM, 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 and other mobile applications,uses the industry’s new 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 7K750 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 7K750 continues HGST’s tradition of ecological leadership and carries its EcoTrac  classification. Travelstar 7K750 delivers speed and capacity, without sacrificing battery life or audio quality,to meet the multi-tasking demands of commercial and consumer users on the go.

Encryption Option

Travelstar 7K750is 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 meet 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 that allow the Travelstar 7K750 to deliver 24x7 access to data for data-intensive applications requiring round-the-clock operation.The 7K750 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.
