Product Benefits

Killer speed – Built on the performance bloodlines of WD Raptor, these

10,000 RPM drives, with SATA 3 Gb/s interface and 16 MB cache, deliver
mind-bending performance. Not only are they 35% faster than the previous
generation of WD Raptor drives, but they also beat out all other competitors in the
field.

Rock-solid reliability – Designed and manufactured to mission-critical

enterprise-class standards to provide enterprise reliability in high duty cycle
environments. With 1.4 million hours MTBF, these drives have the highest available
reliability rating on a high-capacity SATA drive.

Double the capacity – State-of-the-art technology packs twice the capacity per disk

compared to its older brother WD Raptor, resulting in up to 300 GB of
high-performance storage space in this enterprise-class 2.5-inch drive.

Ultra-cool operation – WD VelociRaptor consumes 35% less power than the
previous generation of WD Raptor.

IcePack™ mounting frame - The 2.5-inch WD VelociRaptor is enclosed in a
backplane-ready 3.5-inch enterprise-class mounting frame with a built-in heat sink
that keeps this powerful little drive extra cool when installed in high-performance
desktop chassis.

Note: Not all products
may be available in all

regions of the world.

Rotary Acceleration Feed Forward (RAFF™) – Optimizes operation and

performance when the drives are used in vibration-prone, multi-drive 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.

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, 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 SATA-IO organization as of the date of this specification sheet. Visit www.sata-io.org for details.
