High Performance
24x7 Reliability
1.2 Million Hours MTBF




Interface WD RE3 7200 RPM Enterprise SATA hard drives are packed with
performance and reliability features making them the perfect solution for
SATA servers, video surveillance, and other demanding write-intensive applications.
With a designed, manufactured and demonstrated MTBF of 1.2 million hours
at 100% duty cycle in nominal enterprise conditions, up to 32 MB cache, and
Width/Height best-in-class vibration tolerance, these drives are the ultimate in Enterprise
SATA storage.
3.5-inch/1-inch
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.
