Compatibility: Unlike desktop drives, these drives are tested for compatibility and 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 is. Error recovery controls: WD Red 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 drives are designed to thrive in multi-bay NAS system environments. Desktop Drives vs. WD Red Plus: Do right by your NAS and choose the drive purpose-built 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.
