WD RE4 Enterprise SATA Hard Drives
Ideal for servers, video surveillance, and other demanding write-intensive applications, WD RE4 7200 RPM Enterprise SATA hard drives offer 64 MB cache,4th generation vibration tolerance, and 5-year limited warranty. |
Dual processor
With double the processing power,WD RE4 boasts the highest performance of any drive in the WD RE family. |
RAFF™
Enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant 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. |
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. |
Thermal extended burn-in test
Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation. |
Third generation dynamic fly height
Each read-write head’s fly height is adjusted in real time for optimum reliability. |
24x7 reliability
With 1.2 million hours MTBF (tested at100% duty cycle), these drives have the highest available reliability rating on a high-capacity drive. |
Compatibility
This drive is compatible with any SATA hot swap trays and controllers. |
