R otati onal Vibration Saf eg u ard
(RVS) Feature
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.
