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 WIDTH/HEIGHT ROTATIONAL SPEED CAPACITIES SATA 3.5-inch/1-inch IntelliPower 1.5 TB and 2 TB MODEL NUMBERS Note: Not all products may be available in all regions of the WD2002FYPS world. WD1502FYPS Product Benefits Faster Improved rotary vibration Lower total cost of ownership 24x7 reliability Massive 64 MB cache, dual processors, tolerance Large data-hungry financial institutions With 1.2 million hours MTBF, these drives and increased areal density yield twice and web service providers can save up to have the highest available reliability rating Optimized drive mechanics, system the processing power which results in up $10 savings per drive per year in on a high-capacity drive. characterization, and process validation to 25 percent performance improvement electricity costs (U.S). A large data center yields unmatched performance in high over the previous generation. with 10,000 drives could realize up to vibration environments. $100,000 in savings per year. Greener Improvements in our power-conserving technologies — IntelliSeek™, IntelliPark™, and IntelliPower™— deliver improved power consumption over our previous generation of WD RE-GP drives. Product Features IntelliPower IntelliPark StableTrac™ Rotary Acceleration Feed A fine-tuned balance of spin speed, Delivers lower power consumption by Secures the motor shaft at both ends to Forward (RAFF™) transfer rate, and caching algorithms automatically unloading recording heads reduce system-induced vibration and Optimizes operation and performance designed to deliver both significant power during idle to reduce aerodynamic drag, stabilize platters for accurate tracking when the drives are used in vibration- savings and solid performance. and by disengaging read/write channel during read and write operations. prone multi-drive systems such as Additionally, drives with WD GreenPower electronics. rackmounted servers. Technology consume less current during RAID-specific time-limited error start up allowing more drives to spin up Active Power Management recovery (TLER) simultaneously resulting in faster system readiness. Drives with WD GreenPower Technology Pioneered by WD, this feature prevents monitor the work load and automatically drive fallout caused by the extended hard invoke idle mode whenever possible to IntelliSeek drive error-recovery processes common further reduce unnecessary power to desktop drives. Calculates optimum seek speeds to lower consumption. Drive recovery time from unnecessary power consumption, noise, idle mode is less than one second, and vibration. providing seamless power management between the drive and the host controller.

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.
