High-capacity, high-performance enterprise SATA drives with 24x7
reliability for business-critical applications.
WD RE4 enterprise SATA hard drives combine 64 MB cache with dual
processors 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 up to 2 TB's of
cavernous 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. (2 TB model only)
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.
Perpendicular Magnetic Recording (PMR)
-
WD RE4 drives utilize PMR technology to achieve even greater areal
density, reliability, and design margin.
Active Power Save -
Delivers best-in-class power consumption through advanced WD firmware
that conserves power in active seek modes without degrading performance.
