WD RE4-GP

Power-Saving Hard Drives

Available in capacities up to 2 TB, WD RE4-GP SATA hard drives
offer data-hungry organizations massive capacity with significant
power savings and lower cost of ownership compared to
competitors’ standard enterprise-class drives. These drives are
designed with WD GreenPower Technology™ to deliver power
savings as the primary attribute and are equipped with 64 MB
cache, dual processors, and IntelliPower™, a fine-tuned balance
of spin speed, transfer rate, and caching algorithms designed to
deliver both significant power savings and solid performance.

Faster
Massive 64 MB cache, dual processors,
and increased areal density yield twice
the processing power which results in up
to 25 percent performance improvement
over the previous generation.
Greener
Improvements in our power-conserving
technologies — IntelliSeek™,
IntelliPark™, and IntelliPower™— deliver
improved power consumption over our
previous generation of WD RE-GP drives.
Improved rotary vibration
tolerance
Optimized drive mechanics, system
characterization, and process validation
yields unmatched performance in high
vibration environments.
Lower total cost of ownership
Large data-hungry financial institutions
and web service providers can save up to
$10 savings per drive per year in
electricity costs (U.S). A large data center
with 10,000 drives could realize up to
$100,000 in savings per year.
24x7 reliability
With 1.2 million hours MTBF, these drives
have the highest available reliability rating
on a high-capacity drive.

Product Benefits

Product Features

IntelliPower
A fine-tuned balance of spin speed,
transfer rate, and caching algorithms
designed to deliver both significant power
savings and solid performance.
Additionally, drives with WD GreenPower
Technology consume less current during
start up allowing more drives to spin up
simultaneously resulting in faster system
readiness.
IntelliSeek
Calculates optimum seek speeds to lower
unnecessary power consumption, noise,
and vibration.
IntelliPark
Delivers lower power consumption by
automatically unloading recording heads
during idle to reduce aerodynamic drag,
and by disengaging read/write channel
electronics.
Active Power Management
Drives with WD GreenPower Technology
monitor the work load and automatically
invoke idle mode whenever possible to
further reduce unnecessary power
consumption. Drive recovery time from
idle mode is less than one second,
providing seamless power management
between the drive and the host controller.
StableTrac™
Secures the motor shaft at both ends to
reduce system-induced vibration and
stabilize platters for accurate tracking
during read and write operations.
RAID-specific time-limited error
recovery (TLER)
Pioneered by WD, this feature prevents
drive fallout caused by the extended hard
drive error-recovery processes common
to desktop drives.
Rotary Acceleration Feed
Forward (RAFF™)
Optimizes operation and performance
when the drives are used in vibration-
prone multi-drive systems such as
rackmounted servers.
