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.
