Hitachi HGST Travelstar 7K320 Hard Drives
High Performance Mobile Storage without Sacrificing Capacity or Power
Travelstar 7K320 is the industry’s only fourth generation 7200 RPM 2.5-inch hard drive with capacities ranging from 80GB to 320GB, equivalent to Hitachi 5400 RPM products. The 160GB per platter one and two disk models deliver 60% higher capacity and 12% better application performance than its predecessor. Hitachi provides best-of-breed power and operating shock in Travelstar 7K320 by matching its 5400 RPM models. Designed to support the high-performance needs of multi tasking commercial users and consumers on-the-go, Travelstar 7K320 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.
Data Security Option
Travelstar 7K320 features optional Bulk Data Encryption (BDE) with a SATA 1.5Gb/s 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. Another benefit is that it speeds and simplifies the drive re-deployment process. By deleting the encryption key, the data on the drive is rendered unreadable, thereby eliminating the need for time-consuming data-overwrite.
Enhanced Availability (EA)—for 24x7 Access to Data
Hitachi offers enhanced-availability models that employ specific microcode to allow the Travelstar 7K320 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 7K320 provides high performance, capacity, durability and power utilization on a proven platform for quality and reliability. EA models support the stringent demands of “always-on” applications in lower transaction environments.
