Product Benefits

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.

WIDTH/HEIGHT

3.5-inch/1-inch

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.

ROTATIONAL SPEED

7200 RPM

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.

CAPACITIES

250 GB to 2 TB

Note: Not all products may be available in all regions of the world.

Thermal extended burn-in test

Each drive is put through extended burnin 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.

Applications

Ideal for servers, storage arrays, video surveillance, and other demanding applications.

As used for storage capacity, one megabyte (MB) = one million bytes, on e gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576

bytes. As used for transfer rate or interface, mega byte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATAIO organization as of the date of this specification sheet.
