Western Digital RE4-GP WD2002FYPS 2TB IntelliPower 3.5-inch Enterprise SATA Hard Drive with 64MB Buffer.
Western Digital WD RE4-GP WD2002FYPS 3.5-inch Enterprise SATA Hard Drives 2 TB, 1.2 million hours MTBF, 64 MB Cache, IntelliPower
Faster and greener
With improved performance, lower power consumption and higher capacity, this new generation of WD RE-GP drives provides even lower cost-of-ownership to organizations with large data centers.
This new generation of WD RE-GP drives takes advantage of the performance improvements offered in our WD RE3 family of drives and adds advanced power management technology to deliver a faster, greener solution for large-scale data centers.
Key Features
Faster - 64 MB cache, dual processors, and increased areal density yield twice the processing power results in up to 25% 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 drive.
Improved rotary vibration tolerance - Advanced mechanical optimizations along with system characterization and validation provide the highest performance under vibration conditions of any WD product.
Lower total cost of ownership - Large data-hungry organizations such as financial institutions and web service providers may realize 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 saving per year.
24x7 reliability - With 1.2 million hours MTBF, these drives have the highest available reliability rating on a high-capacity drive.
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. View demo >
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.
Perpendicular Magnetic Recording (PMR) - Employs PMR technology to achieve even greater areal density.
StableTrac - Secures the motor shaft at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations. View demo >
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 rack mounted servers.
Ideal For
Large data centers, web service providers, commercial grade surveillance systems and organizations requiring huge amounts of storage with limited budget and power allotment.

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, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second. |
