Western Digital RE4 Enterprise 500GB SATA/300 7200RPM 64MB Hard Drive - WD5003ABYX w/5-Year WDC Warranty

Massive capacity
WD RE4 Enterprise SATA drives are available with up to 2 TB of cavernous capacity.

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.

Dual actuator technology
A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy. (2 TB only)

StableTrac™
The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations. (1 TB and larger drives only)

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 burning 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 at 100% duty cycle), these drives have the highest available reliability rating on a high-capacity drive.
