with NASware are. Our exclusive
technology takes the guesswork
out of selecting a drive. WD Red
is for small NAS systems, and
our unique algorithm balances
performance and reliability in
NAS and RAID environments.
Simply put, WD Red is the most
compatible drive available for NAS
enclosures. But don’t take our
word for it. WD Red is a reflection
of the most extensive NAS partner
compatibility-testing list that is
available on the market.*

Desktop drives vs. WD Red
In a Network Attached Storage
device, a desktop hard drive is not
designed for NAS environments.
Do right by your NAS and choose
the drive with an array of features
to preserve your data and maintain
optimum performance. Take the
following into consideration when
choosing a hard drive for your NAS:
PERFORMANCE CLASS
5400 RPM Class
• Compatibility: Without being
tested for compatibility with
your NAS system, optimum
performance is not guaranteed.
• Reliability: The always-on
environment of a NAS or RAID is a
hot one. And desktop drives aren’t
typically designed and tested in
those conditions. WD Red is.
• Error recovery Controls: WD Red
NAS hard drives are specifically
designed with RAID error recovery
control to help reduce failures
within the NAS system. Desktop
drives are typically not designed
for RAID environments where this
can be an issue.
• Noise and Vibration Protection:
Designed to operate solo, desktop
drives offer little or no protection
from the noise and vibration faced
in a multi-drive system. WD Red
drives are designed for multi-bay
NAS systems.
WD Red for Home
Stream, backup, share and
organize your digital content
at home with a NAS and
WD Red drives designed to
CAPACITIES
3.5-inch: 1TB to 10TB
2.5-inch: 750GB and 1TB
effortlessly share content to
the devices in your home. Red
NASware increases your drives’
compatibility with your devices,
TV, stereo and more. Live in a
connected world.
WD Red for Small Business
Businesses thrive on productivity
and efficiency – two of the guiding
principles built into the design
of WD Red. It’s the hard drive of
choice for 1 to 8 bay systems.
NASware 3.0 allows for seamless
integration with your existing
network so WD Red can share and
backup files at the speed of your
business. And for larger businesses
with up to 16 bays, count on WD
Red Pro.
WD Red Pro for Big Business
If you’re looking for maximum
performance in a heavy use NAS,
WD Red Pro delivers the same
exceptional performance for
the business customer. For NAS
environments with 8 to 16 bays,
WD Red Pro is designed to handle
an increase in workload and comes
with a 5-year limited warranty.
Applications
WD Red NAS hard drives are recommended for use in home and small office 1–8 bay NAS systems. For systems that use more than 8 bays, please
consider WD Red Pro hard drives.*
* 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 6 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.
