Rotational Vibration Safeguard (RVS) Maintains high performance in multi-drive systems
Enterprise-class features and functions
The DeskstarTM 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.
1TB, 750 and 500GB Balanced power and performance for the enterprise
7200 RPM | SATA 3Gb/s 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.
