Travelstar 7K500 is the industry's only fifth generation 7200 RPM 2.5-inch hard drive with capacities ranging from 120GB to 500GB, matching HGST 5400 RPM capacities. The 250GB per platter one and two disk models deliver up to 56 percent higher capacity and 16 percent better application performance than its predecessor. HGST provides best-of-breed operating shock and outstanding power management in Travelstar 7K500 for sturdy unplugged notebook performance. With its halogen free production and low power consumption, the 7K500 carries the HGST EcoTrac classification. Designed to support the high performance needs of multi-tasking commercial users and consumers on-the-go, Travelstar 7K500 offers speed without sacrificing battery life, capacity or audio quality. HGST offers optional hard drive level encryption for users looking for increased data security and models with enhanced availability to deliver high capacity storage for non stop environments. Travelstar 7K500 features optional Bulk Data Encryption (BDE), now with a 3Gb/s SATA interface, for hard drive level data security. The data is scrambled using a key as it is written to the disk then descrambled with the key as it's retrieved, giving users a higher level of data protection than traditional password based security. It also speeds and simplifies the drive re-deployment process. By deleting the encryption key, the data is rendered unreadable, thereby eliminating the need for time consuming data overwrite. For information about the 7K500 encryption model designed to the Trusted Computing Group Opal specification, please contact your HGST representative. HGST offers enhanced availability models that employ specific microcode to allow the Travelstar 7K500 to provide 24x7 access to data. These models broaden the product line to make it more suitable for data intensive applications requiring around-the-clock operation. The 7K500 provides high performance, capacity, durability and efficient power utilization on a proven platform for quality and reliability. EA models support the stringent demands of (always-on) applications in lower transaction environments.
