Massive capacity

WD RE4 Enterprise SATA drives are
available with up to 2 TB of cavernous
capacity.

Dual processor

With double the processing power,
WD RE4 boasts the highest performance
of any drive in the WD RE family.

RAFF™

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.

Dual 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. (2 TB
only)

StableTrac™

The motor shaft is secured at both ends
to reduce system-induced vibration and
stabilize platters for accurate tracking
during read and write operations. (1 TB
and larger drives only)

IntelliSeek™

Calculates optimum seek speeds to lower
power consumption, noise, and vibration.

Multi-axis shock sensor

Automatically detects the subtlest shock
events and compensates to protect the
data.

RAID-specific, time-limited error
recovery (TLER)

Prevents drive fallout caused by the
extended hard drive error-recovery
processes common to desktop drives.

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.

Thermal extended burn-in test

Each drive is put through extended burn-
in testing with thermal cycling to ensure
reliable operation.

Third generation dynamic fly
height

Each read-write head’s fly height is
adjusted in real time for optimum
reliability.

24x7 reliability

With 1.2 million hours MTBF (tested at
100% duty cycle), these drives have the
highest available reliability rating on a
high-capacity drive.
