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.

Note: Not all products may be

world.

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.

1As 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 buffer or cache, one megabyte (MB) = 1,048,576

bytes. 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. Effective maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATA-

IO organization as of the date of this specification sheet. Visit www.sata-io.org for details.

2WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the European Union for electrical and electronic products. The RoHS Directive 2002/95/EC of the

European Parliament, which is effective in the EU beginning July 1, 2006, aims to protect human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and other substances.
