Ideal for servers, video surveillance and other demanding write-intensive applications.

WD RE SATA hard drives are available in capacities up to 4 TB to suit even the most demanding storage needs.

WD RE delivers up to 6 Gb/s transfer rates, sustained sequential data rates of up to 171 MB/s and high random I/O rates.

With a field-tested 1.2 million hour MTBF, this high performance drive delivers the highest level of reliability for 24x7 operation in up to 100% duty cycle applications.

Twice the processing power to maximize performance.

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.

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 models and above)

The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations. (2 TB models and above)

Automatically detects the subtlest shock events and compensates to protect the data.

Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
