WD RE
SAS Hard Drives
WD RE hard drives are engineered to offer data-hungry SAS
storage systems the massive capacity they need without
compromising top-of-the-line performance. Advanced reliability
and data integrity features allow for 24x7 operation in tightly
packed vibration prone multi-drive systems. This
uncompromising combination of high-capacity, peak
performance and best-in-class reliability make WD RE drives
ideal for business critical applications.

NoTouch
™
ramp load technology
The recording head never touches the
disk media ensuring significantly less
wear to the recording head and media as
well as better drive protection in transit.

Dual stage actuator technology
A head positioning system with two
actuators that improves positional
accuracy over the data track(s). The
primary actuator provides coarse
displacement using conventional
electromagnetic actuator principles. The
secondary actuator uses piezoelectric
motion to fine tune the head positioning
to a higher degree of accuracy.

Vibration Protection
Enhanced RAFF™ technology includes
sophisticated electronics to monitor the
drive and correct both linear and
rotational vibration in real time. The result
is a significant performance improvement
in high vibration environments over the
previous generation of drives.
