Product Benefits
Killer speed
With up to SATA 6 Gb/s interface and
32 MB cache, next generation
10,000 RPM WD VelociRaptor are up to
15% faster than the award-winning
previous generation.
Rock-solid reliability
Designed and manufactured to missioncritical 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.
Monstrous capacity
WD VelociRaptor SATA drives are
available in capacities up to 600 GB,
double the capacity of the previous
generation.
Ultra-cool operation
Consumes less idle power and uses
similar active power as the previous
generation WD VelociRaptor, while
offering double the capacity and higher
performance.
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.
ROTATIONAL SPEED
10,000 RPM
Rotary Acceleration Feed
Forward (RAFF™)
Optimizes operation and performance
when the drives are used in vibrationprone, 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.
CAPACITIES
74, 150, 300, 450, and 600 GB
Note: Not all products may be
available in all regions of the
world.
Environmentally conscious
In addition to being ROHS compliant, this
generation of WD VelociRaptor is also a
halogen free design.
5-year limited warranty

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 specifica tion sheet.
