Desktop drives versus WD Red™ Plus. Choose the drive specifically designed for NAS that is right for your system, with a range of features that will help you protect your data and ensure optimal performance. Consider the following aspects when choosing a hard drive for your NAS: Compatibility: unlike desktop drives, these drives have undergone specific compatibility tests with NAS systems to ensure optimal performance. Reliability: the always-on environments of a NAS or RAID system experience high temperatures. Desktop drives are not usually designed for those conditions or tested for them, whereas WD Red™ Plus drives are. Error recovery controls: WD Red™ Plus hard drives are specifically designed with RAID error recovery control, which helps reduce failures in the NAS system. Noise and vibration protection: designed to operate independently, desktop drives usually offer little or no protection against the noise and vibrations that affect multi-drive systems. WD Red™ Plus drives are designed to excel in multi-bay NAS system environments.
