WD RED: The NAS Drive For Your Network Attached Drive Array

Always Attached - Never Outmatched
With drives up to 10TB, the WD Red drive is built for single-bay to 8-bay NAS systems and packs the capacity to store your precious data in one powerhouse unit.

Cooler Temperatures

By reducing power consumption, the operating temperature of your NAS stays cool. With a lower temperature in your system, you can create a more reliable solution for your NAS.

Built for NAS Compatibility

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

Desktop Drive vs. WD Red Drive

A desktop hard drive is not typically tested and designed for NAS environments. WD Red has features such as NAS compatibility, increased reliability and more.

Exclusive Technologies

WD RED provides seamless integration, robust data protection and optimal performance for NAS systems under heavy demands.



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.


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.


Looking for maximum performance in a heavy use NAS? The WD Red Pro drive is designed to handle an increase in workload and system demand and features a 5-year limited warranty.

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.

True 24/7 Reliability

Since your NAS system is always on, a highly reliable drive is essential for long term reliability. Desktop drives are not designed and tested in 24x7 conditions, which is a foundation of WD Red NAS hard drives.

3 Year Limited Warranty with World-Class Premium Support

Confidently upgrade to the best in NAS drive performance with the assurance of a 3 Year Manufacturer Limited Warranty and world-class support services included with every WD Red drive.
