Product Benefits
Massive capacity - WD RE3 Enterprise SATA drives are available in capacities up to 1 TB.
Rotational Speed
Dual processor - Twice the processing power delivers best-in-class performance for
demanding Enterprise applications.
7200 RPM
RAFFTM - Our fourth generation RAFF technology includes sophisticated electronics to
monitor the drive and correct both linear and rotational vibration for up to a 60% performance
improvement in high vibration environments over the previous generation of drives.
Capacities
IntelliSeekTM - Calculates optimum seek speeds to lower power consumption, noise, and
vibration in active seek modes without degrading performance.
250 GB to 1 TB StableTracTM - The motor shaft is secured at both ends to reduce system-induced vibration
and stabilize platters for accurate tracking during read and write operations. (750 GB and
above)
Model Numbers Multi-axis shock sensor - Automatically detects the subtlest shock events and
compensates to protect the data.
WD1002FBYS RAID-specific, time-limited error recovery (TLER) - Prevents drive fallout caused by the
WD7502ABYS extended hard drive error-recovery processes common to desktop drives.
WD5002ABYS
Third generation dynamic fly height - Each read-write head's fly height is adjusted in real
WD3202ABYS time for optimum reliability.
WD2502ABYS
Thermal extended burn-in test - Each drive is put through extended burn-in testing with
thermal cycling to ensure reliable operation.
NoTouchTM 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
Note: Not all products protection in transit.
