Product Benefits
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
performance for photo and video editing.
Rock-solid reliability
With 1.4 million hours MTBF, these drives
have the highest available reliability rating
on a high capacity SATA drive.
High capacity
State-of-the-art technology delivers a
balance of high performance and high
capacity perfect for data-intensive
workloads that require large amounts of
storage such as video editing, 3D
rendering and scientific modeling.
WIDTH/HEIGHT
3.5-inch/1-inch
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.
Advanced Format (AF)
Technology adopted by WD and other
drive manufacturers as one of multiple
ways to continue growing hard drive
capacities. AF is a more efficient media
format that enables increased areal
densities.
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
250 and 500 GB; 1 TB
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.
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.
5-year limited warranty
Applications
High-performance computing, 3D rendering, digital content creation and editing, scientific computing and image management.

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.
