High-performance mobile storage without sacrificing capacity or power
Travelstar 7K500 is the industry’s only fifth-generation 7200 RPM 2.5-inch hard drive with capacities ranging from 120GB to 500GB, matching Hitachi 5400 RPM capacities. The 250GB per platter one- and two-disk models deliver up to 56% higher capacity and 16% better application performance than its predecessor. Hitachi 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 Hitachi 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. Hitachi 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.
Encryption and TCG Opal specification
Travelstar 7K500 features optional Bulk Data Encryption (BDE), now with a 3Gb/s SATA interface, for hard-drive-level data security. A new encryption model of the 7K500 conforms to the Trusted Computing Group Opal specification, supporting industry standardization. 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.
