* Compatibility: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems for optimum performance.  
* Reliability: The always-on environment of a NAS or RAID is a hot one, and desktop drives aren’t typically designed and tested under those conditions like  WD Red™ Pro drives are. 
* Error Recovery Controls:  WD Red™ Pro NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. 
* 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™ Pro drives are designed to thrive in multi-bay NAS system environments.
