Hitachi HGST DeskStar E7K1000 3.5" Enterprise Hard Drive
Enterprise-Class Features and Functions
The Deskstar E7K1000 delivers value to the enterprise with up to 1TB of capacity, 7200 RPM performance and innovative technologies like Rotational Vibration Safeguard (RVS). Systems with multiple drives installed are at risk for rotational vibration disturbance, which results from simultaneous operation of neighboring drives. To mitigate any adverse impact on system performance, Hitachi-patented RVS technology works to counteract this disturbance ensuring drive performance and data integrity. With a SATA 3Gb/s interface which utilizes the same physical connector as Serial Attached SCSI (SAS) drives, the Deskstar E7K1000 is ideal for use in mixed-drive enterprise environments. The drive also has a targeted 1.2 million hours MTBF rating and provides the industry’s most comprehensive 5-year warranty.
Balanced Power and Performance for the Enterprise
The Deskstar E7K1000 hard drive provides an exceptional blend of power efficiency and performance making it an ideal solution for power conscious enterprises. Leveraging seventh generation power management technology, as well as power-saving innovations pioneered on the popular 2.5-inch line of notebook hard drives from Hitachi, this new breed of drive delivers best-in-class power management and thermal emissions to help manufacturers meet energy compliance targets and extend drive life.
Data Security Option
Deskstar E7K1000 offers optional Bulk Data Encryption (BDE) that uses an Advanced Encryption Standard (AES) certified by the National Institute of Standards and Technology (NIST) to deliver the strongest commercially available data security protection. Data is scrambled using a key as it is written to the disk then descrambled with the key as it is retrieved. It also 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. For information on how to order this optional feature, contact your Hitachi sales representative.
