Rotational Vibration Safeguard
(RVS) Feature
The Hitachi Deskstar E7K500 extends the company’s long-standing tradition of performance
and reliability leadership. Hitachi’s enterprise features for storage applications enable high
capacity, fast transfers, low power and high reliability. These features combine to make the
Deskstar E7K500 ideal for nearline/low duty cycle, disk-to-disk back-up and other enterprise
storage solutions.
The Deskstar E7K500 hard drive is optimized
for use in nearline/low duty cycle enterprise
environments with capabilities such as
Rotational Vibration Safeguard (RVS), which
maintains the hard drive’s performance in high
rotational vibration environments where
multiple drives reside in a single enclosure.
The Deskstar E7K500 carries the industry’s most comprehensive 5-year warranty with
product replacement values throughout the life of the warranty that exceed those
available from other hard drive suppliers.
Advanced Serial ATA 3.0Gb/s Support
> 3.0 Gb/s (300 MB/s) interface data rate
> NCQ (native command queuing)
> Staggered (delayed) spin-up
> Hot-swap capability
The E7K500 provides all of these enhancements
to enable faster data access, better power
management to the system and higher
performance.
