WD 4TB Red Plus WD40EFZX NAS Hard Drive 3.5-Inch

Key features

#1: Compatibility                                       
Unlike desktop drives, these 3.5” HDDs are specifically tested for compatibility with NAS systems for optimum performance.  
#2: 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. 
#3: 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. 
#4: 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
