Exclusive NASware™ 3.0

Not just any drive will do. In single-bay to 8-bay NAS systems, WD Red drives raise the

bar. Get as much as 112TB capacity, and with WD’s exclusive NASware™ technology, you

can optimize every single one of them. Built into every WD Red hard drive, NASware 3.0’s

advanced technology improves your system’s storage performance by increasing compati-

bility, integration, upgradeability, and reliability.

Built for optimum NAS compatibility

Desktop drives aren’t purpose-built for NAS. But WD Red drives with NASware technology

are. Our exclusive technology takes the guesswork out of selecting a drive. WD Red drives

are for small NAS systems, and our unique algorithm balances performance and reliability

in NAS and RAID environments. Simply put, a WD Red drive is one of the most compati-

ble drives available for NAS enclosures. But don’t take our word for it. WD Red drives are

a reﬂection of extensive NAS partner technology engagement and compatibility-testing

resulting in a leading compatibility list for NAS systems.

Desktop Drives vs. WD Red

In a Network Attached Storage device, a desktop hard drive is not typically designed for

NAS environments. Do right by your NAS and choose the drive designed 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: Without being tested for compatibility with your NAS system, optimum

performance is not guaranteed.

• Reliability: The always-on environment of a NAS or RAID is a challenging one. And

desktop drives aren’t typically designed and tested under those conditions. WD Red

drives are.

• Error recovery controls: WD Red NAS hard drives are speciﬁcally designed with RAID

error recovery control to help reduce failures within the NAS system. Desktop drives are

not typically designed for RAID environments.

• 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 drives are designed for multi-bay NAS systems.

WD Red for Home

Stream, backup, share, and organize your digital content at home with a NAS and WD Red

drives designed to effortlessly share content with the devices in your home. NASware 3.0

technology increases your drives’ compatibility with your devices, TV, stereo, and more.

Live in a connected world.

WD Red for Small Business

Businesses thrive on productivity and efﬁciency—two of the guiding principles built into

the design of WD Red drives. It’s the hard drive of choice for 1 to 8 bay systems. NASware

3.0 technology allows for seamless integration with your existing network so WD Red can

share and backup ﬁles at the speed of your business. And for larger businesses with up to

24-bays, count on WD Red Pro™ drives.

WD Red Pro for Big Business

If you’re looking for maximum performance in a heavy use NAS, WD Red Pro drives deliver

the same exceptional performance for the business customer. For NAS environments with 8

to 24 bays, WD Red Pro drives are designed to handle an increase in workload and comes

with a 5-year limited warranty.
