WD GREEN
Desktop Hard Drives
WD Green hard drives are designed for use in systems that
require cool and quiet operation, as secondary drives in PCs,
for external enclosures and other applications for which low
noise and low heat are benecial. These earth-friendly hard
drives are ideal for use whenever energy efciency is needed.

Product Features
WD’s commitment to sustainability – WD’s green initiative goes beyond the
product level, focusing on recycling and improving the cleanliness of the air,
water and land.
Leading the way to green hard
drives – WD led the industry in
creating a new category of hard
drives that use less power and
helps to reduce the world’s energy
demands one computer user at
a time. With over 90 million WD
Green drives sold* customers using
WD Green drives have saved the
planet over 466 million kwh of
power – nearly equaling the annual
power production of a single coal
power plant!
*Data reects approximate drives sold as of March 2012.
Conict-free materials – As a
leader in hard drive manufacturing,
WD proudly guarantees our hard
drives are built with 100% conictfree raw materials.
Halogen free – In addition to being
RoHS compliant, all WD Green
drives are lead and halogen free,
resulting in less pollutants getting
into our environment.
Reduced rare earths
dependency – WD’s nextgeneration WD Green hard drives
are built using less rare earth
minerals.
Applications
ROTATIONAL SPEED
IntelliPower™
Reduced power consumption
Best-in-class power management
technology delivers signicant power
savings and solid performance.
Cool and quiet
WD GreenPower Technology™ yields
lower operating temperatures for
increased reliability and low acoustics
perfect for ultra-quiet PCs and
external drives.
NoTouch™ ramp load technology
The recording head never touches
the disk media ensuring signicantly
less wear to the recording head
and media as well as better drive
protection in transit.
CAPACITIES
500 GB to 3 TB
Note: Not all products may be
available in all regions of the world.
IntelliSeek
Calculates optimum seek speeds to
lower power consumption, noise and
vibration.
Tested for compatibility
We perform tests on hundreds of
systems and a multitude of platforms
in our FIT Lab™ to give our customers
condence that our drives will work in
their systems.
™
WD Green hard drives are tested and recommended for use as secondary storage in PCs, external enclosures and applications that require cool and
quiet operation. Desktop drives are not recommended for use in RAID environments. Please consider using WD Red™ hard drives for home and small ofce 1-5
bay NAS systems and WD enterprise hard drives for rackmount and NAS systems with more than 5 bays.*
* WD hard drives are designed and tested for use in specic applications and environments. This ensures that your hard drive is compatible with and functions properly in your application.
Our hard drives are warranted against defects in materials and workmanship in the system for which they were designed. Use in systems other than for what the hard drive was
designed could result in compatibility problems that affect proper function, unrelated to material and/or workmanship defects. For best results, be sure to select the appropriate product
for your application by consulting our product spec sheets on our website at www.wd.com or by calling our customer support line where we would be happy to help you through the
selection process.

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 specication published by the SATA-IO organization as of the date of this specication
sheet. Visit www.sata-io.org for details.
