Tuned for NAS with NASware
Western Digital's exclusive NASware technology fine tunes drive parameters to match NAS system workloads, which helps increase performance and reliability.
Designed for Continuous Operation
Since your NAS system is always on, a reliable drive is essential. WD Red Plus hard drives are designed for systems that operate 24/7, giving users the confidence of knowing they can reliably access their data.
Tested for Dependable Compatibility
Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures.
Optimized for Lower TCO
WD Red Plus drives are engineered to use less power (versus previous models) and run cooler, which reduces operating costs and helps reduce heat in thermally challenged NAS boxes.
Powered for Strong Performance
Despite using less power, the drives have plenty of bandwidth to handle the mixed performance demands of multi-drive NAS systems.
Balanced for Increased Reliability
Hard drives that are not properly balanced may cause excessive vibration and noise in multi-drive systems, which could reduce hard drive life span and degrade the performance over time. WD's enhanced dual-plane balance control technology significantly improves balance and increases overall drive performance and reliability.
Limited 3-Year Warranty
Western Digital stands behind their NAS storage solutions with the assurance of a limited 3-year limited warranty and world-class support services for hassle-free data storage.
Desktop Drives vs. WD Red Pro
Compatibility
Unlike desktop drives, WD Red hard drives are specifically designed and tested for NAS and include NASware technology which fine tunes drive parameters to match NAS system workloads for optimum performance.
Reliability
Desktop drives aren't typically designed for the demands of an always-on NAS environment. WD Red hard drives are designed to perform under tough conditions encountered in high-intensity 24/7 multi-user NAS environments.
RAID Ready
WD Red hard drives are engineered with RAID error recovery control to help reduce failures within multi-bay NAS systems, unlike most desktop drives that are configured for generic use.
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 hard drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration often found in multi-bay NAS systems.

WD Plus Reviews

Silent and reliable NAS drive

By Oleksii
Rated 5 out of 5

Great NAS drive for home use. I'm using it for Time Machine backup and as an archive drive. Completely silent — you can't hear it at all even in a quiet room. Works perfectly and reliably. My only wish is that WD would release larger capacities in the Red Plus 5400 RPM line — 6TB is great but more would be even better. Highly recommend for anyone looking for a quiet and reliable NAS drive.

A brown out damaged a drive in my nas. Bought original from BH 4 years ago. This went right in and everything worked great.

See any errors on this page?

Are these new drives CMR or SMR? Thanks
