WD Green:

WD GreenDesktop SATA Hard Drives

Cool And Quiet Storage With Massive Capacity.
WD Green storage is designed specifically with reliability in mind for an increased drive lifespan. The advantage of being cool and quiet impacts overall reliability while reduced heat output, decreased power consumption, quiet acoustics, and best-in-class power management make WD Green a leader when compared to the competition.

The advantage of cool & quiet

The advantage of cool & quiet
Heat has a large impact on the overall reliability of a HDD's life over time. It can also lead to increased power consumption, the requirement of additional fans and increased fan operation, increased noise levels and the increased chance of failure. WD Green drives come equipped with WD GreenPower Technology which allows the drive to operate cooler with increased overall reliability.

Power management with performance

Power management with performance
Best-in-class power management, reduced heat output, and next-generation technologies such as IntelliSeek offer a perfect balance of performance and power, making WD Green a leader in performance when compared to the competition.

Reliability with an increased lifespan

Reliability with an increased lifespan
Quiet acoustics, reduced vibration and advanced 4K HDD formatting makes WD Green a stronger solution when compared to the competition and perfect for PCs and external drive applications.

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!

Reduced power consumption
WD Green drives deliver both significant power savings and solid performance. These drives also consume less current during startup allowing lower peak loads on systems as they are booted.

NoTouch ramp load technologyNoTouch 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.

Eco-conscious
WD Green drives are innovatively designed and manufactured with lead-free, conflict-free and halogen-free materials to help ensure a sustainable future.

Reduced rare earths dependency.
WD's next-generation WD Green hard drives are built using less rare earth minerals.

Conflict-free materials.
As a leader in hard drive manufacturing, WD proudly guarantees our hard drives are built with 100% conflict-free raw materials.

Cool and quiet
WD GreenPower Technology™ yields lower operating temperatures for increased reliability and low acoustics perfect for ultra-quiet PCs and external drives.

WD GreenPower Technology

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.

IntelliSeek.
Calculates optimum seek speeds to lower power consumption, noise and vibration.

IntelliPower.
A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance. Additionally, WD Green Desktop drives consume less current during startup allowing lower peak loads on systems as they are booted.

Advanced Format (AF)Advanced Format (AF).
Technology being 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. (RX, RS and RSDTL models only)

Upgrading your drive is easy.
WD Acronis TrueImage, available as a free download on the WD Support website, enables you to copy all your data to a new drive so you don't have to reinstall your operating system to get all the benefits of a new drive.

Tested for compatibility
We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab™ to give our customers confidence that our drives will work in their systems.

Recommended use.
WD Green storage is tested and recommended for primary use in desktop and All-in-One PCs, as secondary storage for archiving, in external cases or as reliable backup storage.*

* Desktop drives are not recommended for use in RAID environments, please consider using WD Red hard drives for desktop RAID environments or WD datacenter hard drives for rackmount or large RAID configurations.
1 Not all products may be available in all regions of the world.
2 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.
