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.
