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 300 GB of
high-performance storage space in this enterprise-class 2.5-inch drive.
Small form factor – This ultra fast 2.5-inch hard drive is engineered to fit into blade
servers and other enterprise storage configurations. (Not designed for use in laptop
or notebook computers)
Ultra-cool operation – WD VelociRaptor consumes 35% less power than the
previous generation of WD Raptor.
Rotary Acceleration Feed Forward (RAFF™) – Optimizes operation and
performance when the drives are used in vibration-prone, multi-drive chassis.
Note: Not all products
may be available in all
regions of the world.
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, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one
billion bits per second. Effective maximum SATA 3 Gb/s or 1.5 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.
