WD RE4
enterprise SATA hard drives combine 64
MB cache with SATA 3 Gb/s transfer rate
and dual stage actuation for
lightning-fast performance in demanding
server and storage applications.
Technologically advanced acoustics
minimize noise. Cool drive operation and
enhanced reliability features help
protect the drive and the data stored on
it.
Key Features
Massive
capacity - WD RE4 Enterprise SATA
drives are available with a cavernous 2
TB capacity.
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.
Dual
processor - With double the
processing power, WD RE4 boasts the
highest performance of any drive in the
WD RE family.
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.
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.
IntelliSeek
- Calculates optimum seek speeds to
lower unnecessary 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.
Third
generation dynamic fly height - Each
read-write head’s fly height is adjusted
in real time for optimum reliability.
Thermal
extended burn-in test - Each drive
is put through extended burn-in testing
with thermal cycling to ensure reliable
operation.
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.
Active Power Save
- Delivers best-in-class power
consumption through advanced WD firmware
that conserves power in active seek
modes without degrading performance. |
