The drive for NAS
Desktop drives aren’t typically tested or designed for the rigors of a NAS system. Do right by your NAS and choose the drive with an array of features to help preserve your data and maintain optimum performance.

Built for NAS Compatibility
WD Red drives with NASware 3.0 technology are purpose-built to balance performance and reliability in NAS and RAID environments.

Keep it Cool
The always-on environment of a NAS or RAID is a hot one. WD Red drives are engineered to run cool and quiet while offering optimum compatibility for demanding 24x7 environments.

WD Red For Home
Stream, backup, organize and effortlessly share your digital content to your TV, PC and more. NASware technology increases your drives' compatibility with your NAS system, for better playback with your devices.

WD Red For Small Business
Businesses thrive on productivity and efficiency, two guiding principles built into the design of the WD Red drive. Share and backup files at the speed of your business with a WD Red drive in your NAS.

Designed For NAS
Desktop drives aren't purpose-built for NAS. But WD Red drives with NASware 3.0 are. Our exclusive technology takes the guesswork out of selecting a drive. We can help you find the perfect storage for your NAS system.

3D Active Balance Plus
Helps to ensure your data is protected from excessive vibration and noise in a NAS or RAID environment. This dual-plane balance control maintains your drive’s performance over time.

24/7 Environment
Since your NAS system is always on, a reliable drive is essential. Desktop drives are not typically designed and tested in 24x7 conditions, which is a foundation of WD Red NAS hard drives.

Exclusive Technology
Seamless integration, robust data protection and optimal performance for NAS systems under heavy demand.
