	Ideal for servers, video surveillance, and other demanding write-intensive applications, WD RE4 7200 RPM Enterprise SATA hard drives offer massive 2 TB capacity, 64 MB cache, 4th generation vibration tolerance and 5-year limited warranty. Massive capacity - WD RE4 Enterprise SATA drives are available with a cavernous 2 TB capacity. 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. 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. Perpendicular Magnetic Recording (PMR) - WD RE4 drives utilize PMR technology to achieve even greater areal density, reliability, and design margin. Active Power Save™ - Delivers best-in-class power consumption through advanced WD firmware that conserves power in active seek modes without degrading performance.
