The 6TB TB WD RE SATA 3.5" OEM Hard Drive from WD is a powerful combination of enterprise-class performance and high capacity required for superior performance computing and business critical environments. The hard drive delivers transfer rates of up to 6 Gb/s and high random I/O rates. It is coupled with a dual processor, which provides twice the processing power to maximise performance.

Key Features

High Performance for Business Critical Applications

The hard drive delivers transfer rates of up to 6 Gb/s and high random I/O rates.

Designed for Quality and Reliability

The WD RE SATA Hard Drive, with a field-tested 1.2 million hours MTBF delivers the highest level of reliability. It also provides advanced level of reliability for 24x7 operation in up to 100% duty cycle applications.

Dual Processor

The hard drive features a dual processor, which provides twice the processing power to maximise performance.

Vibration Protection

The enhanced RAFF technology monitors the drive and corrects both linear and rotational vibration in real-time. It thus provides optimum performance even in high vibration environments.

Dual Actuator Technology

The WD RE SATA Hard Drive features a head positioning system with two actuators which 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.


The motor shaft is secured at both ends to reduce system-induced vibration and stabilise platters. It thus enables accurate tracking of read and write operations.

Multi-Axis Shock Sensor

The multi-axis shock sensor feature automatically detects the subtlest shock events and compensates to protect the data.

RAID-Specific Time-Limited Error Recovery (TLER)

This feature prevents drive fall-out 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. This ensures significantly less wear to the recording head and media as well as better drive protection in transit.

Thermal Extended Burn-In Test

The hard drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.

Dynamic Fly Height Technology

Each read-write head's fly height is adjusted in real-time for optimum reliability.


The WD RE SATA Hard Drive is ideal for servers, video surveillance and other demanding write-intensive applications.
