As demand for storage continues to expand, the need for more efficient power 
solutions becomes paramount. WD RE2-GP enterprise SATA hard drives make 
it possible for large-scale data centers to increase storage capacity without 
exceeding available power, and in many cases actually reducing power 
consumption. WD RE2-GP drives help combat the four major challenges large 
data installations face—total drive slots, maximum capacity, power allotment, and 
financial constraints—while lowering the total cost of ownership. 

Product Benefits

Reduced power consumption 

 

The combination of WD’s IntelliSeek

, IntelliPark

, and 

IntelliPower

 technologies brings optimized performance at industry-leading low power 

consumption; power is reduced as much as 40 percent.

Helps enable eco-friendly servers 

— Each WD RE2-GP drive consumes an average of 

4-5 watts less than competitor drives making it possible for energy-conscious customers 
to build servers with higher capacities, ensured reliability, and promote energy 
conservation. 

Lower total cost of ownership 

— Large data-hungry financial institutions and web 

service providers can save up to $10 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.

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 disengages read/write 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 (750 GB and 
1 TB models only).

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.

1.2 million hours MTBF 

— The highest available reliability rating on a high-capacity drive.
