Dual processor: Twice the processing power results in a 20% performance improvement over the previous generation.
RAFF: Our 4th generation RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration simultaneously, 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 in active seek modes without degrading performance.
Multi-axis shock sensor: An additional 3rd 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.
Perpendicular Magnetic Recording (PMR): WD RE3 drives utilize PMR technology to achieve even greater areal density.
