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 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 RE3 drives utilize PMR technology to achieve even greater areal density, reliability, and design margin.
