Western Digital Re WD2503ABYZ 250GB Enterprise 3.5″ SATA Hard Drive
| WD Re Datacenter SATA Hard Drives Ideal for servers, video surveillance, and other demanding write-intensive applications, WD Re 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 Re boasts the highest performance of any drive in the WD 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. |
24×7 reliability With 1.2 million hours MTBF (tested at100% duty cycle), these drives have the highest available reliability rating on a high-capacity drive. |
