NAS HARD DRIVES
There’s a leading edge WD Red drive for every compatible NAS system
to help fulfill your data storage needs. With drives up to 14TB, WD Red
drives offer a wide array of solutions for customers looking to build a NAS
storage solution. Built for single-bay to 8-bay NAS systems, WD Red drives
pack the power to store your precious data in one powerhouse unit. With
WD Red drives, you’re ready for what’s next.
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 compatibility, 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 compatible 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 recover y 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 per formance 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.
