WD RE4-GP Power-saving Hard Drives

24x7 reliability

–

With 1.2 million hours MTBF, these drives have

the highest available reliability rating on a high-capacity drive.
IntelliPower

–

A fine-tuned balance of spin speed, transfer rate,

and caching algorithms designed to deliver both significant power
savings and solid performance.
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

–

WD drives with GreenPower™

technology monitor 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 rack mounted servers.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total
accessible capacity varies depending on operating environment. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per
second, and gigabit per second (Gb/s) = one billion bits per second.
