WD RE4 WD2503ABYX - hard drive - 250 GB - SATA 3Gb/s

Key Features and Benefits: Dual actuator technology A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy. Dual processor With double the processing power, WD RE4 boasts the highest performance of any drive in the WD RE family. StableTrac The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations. RAFF Enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives. IntelliSeek Calculates optimum seek speeds to lower power consumption, noise, and vibration in active seek modes without degrading performance. Multi-axis shock sensor Automatically detects the subtlest shock events and compensates to protect the data. RAID-specific, time-limited error recovery (TLER) Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. Third generation dynamic fly height Each read-write head's fly height is adjusted in real time for optimum reliability. Thermal extended burn-in test Each drive is put through extended burn in testing with thermal cycling to ensure reliable operation. NoTouch ramp load technology The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit. Active Power Save Deliver best-in-class power consumption through advanced WD firmware that conserves power in active seek modes without degrading performance.
