Western Digital RE4-GP Product Overview - Page 1

WD RE4-GP Power-Saving Hard Drives 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. These drives are designed with WD GreenPower Technology™ 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. INTERFACE SATA MODEL NUMBERS WD2002FYPS WD1502FYPS WIDTH/HEIGHT 3.5-inch/1-inch ROTATIONAL SPEED IntelliPower CAPACITIES 1.5 TB and 2 TB Note: Not all products may be available in all regions of the world. Product Benefits Faster Massive 64 MB cache, dual processors, and increased areal density yield twice the processing power which results in up to 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, 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. 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. 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 vibrationprone multi-drive systems such as rackmounted servers.
