WD RE4-GP

Power-Saving Hard Drives

Faster Performance

Reduced Power Consumption

Lower Cost of Ownership

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. Based on WD's
exclusive GreenPower™ platform, these drives are designed 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.

Product Benefits

Faster

— 64 MB cache, dual processors, and increased areal density yield twice the

processing power which results in up to a 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 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,
GreenPower

™

drives 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

—

WD GreenPower drives 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 rackmounted
servers.
