Product Benefits
Massive capacity
WD RE4 Enterprise SATA drives are available with up to 2 TB of cavernous capacity.
Dual actuator technology
A head positioning system with two actuators that improves positional accuracy over the data track(s). [. . . ] The result is a significant performance improvement in high vibration environments over the previous generation of drives.
StableTracTM
The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.
NoTouchTM 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.
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.
IntelliSeekTM
Calculates optimum seek speeds to lower power consumption, noise, and vibration.
Applications
Ideal for servers, storage arrays, video surveillance, and other demanding applications.

1 As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. As used for transfer rate or interface, megabyte 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. 2 Controlled unload at ambient condition 3 The term of the limited warranty may vary by region. 4 No non-recoverable errors during operating tests or after non-operating tests. 5 Sound power level.
