  • 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.
