User manual WESTERN DIGITAL WD RE2-GP DATASHEET

[. . . ] WD RE2-GP Power-Saving Hard Drives Reduced Power Consumption Environmentally Responsible Lower Cost of Ownership Enterprise Hard Drives Interface SATA Width/Height 3. 5-inch/1-inch 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. [. . . ] 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. StableTracTM -- 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 (RAFFTM) 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.
