WD 4TB 3.5" SATA III INT. HDD 128MB CACHE RED PLUS (WD40EFPX)
Compatibility: Unlike desktop drives, these 3.5” HDDs 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™ Plus drives are.
Error Recovery Controls: WD Red™ Plus 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™ Plus drives are designed to thrive in multi-bay NAS system environments.
