Desktop Drives vs. WD RedTM Pro
Do right by your NAS and choose the drive purpose-built for NAS with an array of features to help
preserve your data and maintain optimum performance. Take the following into consideration when
choosing a hard drive for your NAS:
• Compatibility: Unlike desktop drives, these drives
are specifically tested for compatibility with NAS
systems for optimum performance.
• Reliability: The always-on environment of a NAS
or RAID is a hot one, and desktop drives aren’t
typically designed and tested under those
conditions like WD RedTM Pro drives are.
• Error Recovery Controls: WD Red Pro NAS hard
drives are specifically designed with RAID error
recovery control to help reduce failures within the
NAS system.
• Noise and Vibration Protection: Designed to
operate solo, desktop drives typically offer little
or no protection from the noise and vibration
present in a multi-drive system. WD Red Pro
drives are designed to thrive in multi-bay NAS
system environments.
NAS HARD DRIVES
For the Demands of Big Business
Designed specifically with medium or large scale business customers in mind, WD
RedTM Pro drives are available for up to 24-bay NAS systems. Engineered to handle
high-intensity workloads in 24×7 environments, WD Red Pro is ideal for archiving and
sharing, as well as RAID array rebuilding on extended operating systems such as ZFS or
other file systems. These drives add value to your business by enabling your employees to quickly share their files and back-up folders reliably in your NAS solution.
Exclusive NASware™ 3.0 Technology
Our exclusive advanced firmware technology, NASware™ 3.0, enables seamless integration, robust data protection and optimal performance for NAS systems operating
under heavy demand. Built into every WD Red Pro hard drive, NASware 3.0’s advanced
technology improves storage performance by increasing compatibility, integration,
upgradeability, and reliability.
Built for Optimum NAS Compatibility
WD Red Pro drives with NASware technology takes the guesswork out of selecting
a drive. Optimized for NAS systems, our unique algorithm 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 NAS enclosures. But don’t take our word for it.
WD Red Pro drives are a reflection of extensive NAS partner technology engagement
and compatibility-testing.
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 24-bay NAS environments and helps increase
hard drive reliability.
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.
Error Recovery Prevention
Built specifically for RAID and NAS environments, WD Red Pro drives come equipped
with error recovery controls as par t of NASware 3.0 technology to help reduce drive
fallout in RAID applications.
Extended Drive Testing
A NAS environment that has up to 24 bays is very demanding on a hard drive with added vibration and heat. This is why every WD Red Pro drive is shipped with extended
thermal cycle burn-in testing to help ensure each drive is tested for extended reliable
operation.
Longer Warranty Coverage
WD Red Pro drives comes with a 5-year limited warranty for an even greater peace of
mind.

MTBF spe cifications are ba sed upon interna l testing using a 40 °C base castin g temperature. MTB F is based on
a sample population and is estimated by statistical measurements and acceleration algorithms. MTBF does not
predic t an individual dr ive’s reliabilit y and does not cons titute a war ranty.
Workloa d Rate is defined as the a mount of user data t ransferred to or f rom the hard drive. Wor kload Rate is
annual ized (TB transfe rred x (8760 / record ed power-on ho urs)). Workloa d Rate will vary de pending o n your
hardware and software components and configurations.
