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.
