technology, NASware 3.0 enables
seamless integration, robust
data protection and optimal

Built for optimum NAS
compatibility

Desktop drives aren’t purpose­built for NAS. But WD Red
Pro drives with NASware 3.0
technology are purpose-built for
NAS. Our exclusive technology
takes the guesswork out of
selecting a drive and balances
performance and reliability in
NAS and RAID environments.
Simply put, a WD Red Pro drive
is one of the most compatible
drives available for medium to
large NAS enclosures. But don’t
take our word for it. WD Red
Pro drives are a reflection of an
extensive NAS partner technology
engagement and compatibility­testing resulting in a leading
compatibility list for NAS systems.

CAPACITIES

2TB to 10TB

Larger NAS Bay Shock Protection

WD Red Pro drives are equipped
with a multi-axis shock sensor
that automatically detects subtle
shock events and dynamic
fly height technology which
adjusts each read-write function
to compensate and protect
the data. This combination of
technology further protects the
drives in larger 1 to 16 bay NAS
environments and helps increase
hard drive reliability.

Applications

Specifically targeted at the medium to large business NAS applications with 1–16 bays.*

*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.

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

Product MTBF specifications are based upon a 40°C base casting temperature and typical system workload of 300TB/year. Workload is defined as the amount of user data transferred to or from the hard drive.

6

See http://support.wd.com/warranty for regional specific warranty details.

7

No non-recoverable errors during operating tests or after non-operating tests.

8
