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 employ-

ees 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 inte-

gration, 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 technol-

ogy 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 part 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 add-

ed 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.

WD Red™ Pro

Desktop Drives vs. WD RedTM Pro

Do right by your NAS and choose the drive pur-

pose-built for NAS with an array of features to help

preserve your data and maintain optimum perfor-

mance. 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.
