From the Manufacture

WD RE3 Enterprise SATA hard drives are packed with performance features including a SATA 3 Gb/s interface, up to 32 MB cache, and an ultra-fast dual processor. Enhanced reliability features, including fourth  generation RAFF technology make these drives the easy choice for servers, storage arrays, video surveillance, and other demanding write-intensive applications. 

Features at a glance:

Massive capacity- WD RE3 Enterprise SATA drives are available in capacities up to 1 TB.

Dual processor - Twice the processing power results in a 20% performance improvement over the previous generation.

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 - Our fourth generation RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time for up to a 60% performance improvement in high vibration environments over the previous generation of drives

IntelliSeek - Calculates optimum seek speeds to lower unnecessary power consumption, noise, and vibration in active seek modes without degrading performance.

Multi-axis shock sensor — An additional third sensor has been added to automatically detect subtle high frequency shock events in all axis enabling compensation 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.
