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
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
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.
™
drives consume less current during start up allowing more drives to spin up
™
— Secures the motor shaft at both ends to reduce system-induced vibration

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 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

WD products manufactured and sold worldwide after August 1, 2005, 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.
