Product Features
NAS compatibility
WD eliminates the confusion.
WD Red is the only hard drive
designed for NAS systems that
have 1 to 5 drive bays. The drives
are designed and extensively tested
for compatibility in the unique 24x7
operating environment and
demanding system requirements of
home and small business NAS.
Enhanced reliability
With a 35% MTBF improvement
over standard desktop drives, the
WD Red drive is designed and
manufactured to be a more reliable
and robust solution.
The secret is in the
technology–NASware™
Advanced firmware technology built
into every WD Red drive, enables
seamless integration, robust data
protection and optimal performance
for systems operating in NAS and
RAID environments.
Energy efficient
Innovative technology reduces
power consumption and lowers the
operating temperature, resulting in a
more reliable and affordable solution
for always on 24x7 NAS
environments.
3D Active Balance Plus
Our enhanced dual-plane balance
control technology significantly
improves the overall drive
performance and reliability. Hard
drives that are not properly
balanced may cause excessive
vibration and noise in a multi-drive
system, reduce the hard drive life
span, and degrade the performance
over time.
Longer warranty coverage
The WD Red drive is backed by a
3-year limited warranty for greater
peace of mind.

Applications
WD Red NAS hard drives are recommended for use in home and small office 1-5 bay NAS systems. For systems that use more than 5 bays or are rack mount
solutions, please consider WD enterprise hard drives.*
* WD hard drives are designed and tested for use in specific 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.

1As 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 specification published by the SATA-
IO organization as of the date of this specification sheet. Visit www.sata-io.org for details.
