Ultra fast.
Designed around a 10,000 RPM spin speed, these SATA 6 Gb/s drives include a 64 MB cache and deliver the ultimate in performance.
Monstrous capacity
WD VelociRaptor SATA drives are available in capacities up to 1 TB, 66% greater capacity than the previous generation.
Rock-solid reliability
With 1.4 million hours MTBF, these drives have the highest available reliability rating on a high capacity SATA drive.
Ultra-cool operation
Consumes less idle power and uses similar active power as the previous generation WD VelociRaptor, while offering higher capacity and performance.
IcePack™ mounting frame
The 2.5-inch hard drive is enclosed in a backplane-ready 3.5-inch mounting frame with a built-in heat sink that keeps this powerful little drive extra cool when installed in high-performance desktop chassis.
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.
Pre-emptive Wear Leveling (PWL)
Ensures reliability for applications that perform a high incidence of read/write operations at the same physical location on the disk.
Rotary Acceleration Feed Forward (RAFF™)
Optimizes operation and performance when the drives are used in vibration-prone, multi-drive chassis.
Environmentally Conscious
In addition to being RoHS compliant, this generation of WD VelociRaptor also provides a halogen-free design.

As used for storage capacity, one megabyte (MB) = one million bytes, one 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, megabyte per second (MB/s) = one million bytes per second, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second.
WD VelociRaptor drives devour the competition with unrivaled performance.
