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:

  • Compatibility: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems for optimum performance.
  • Reliability: The always-on environments of NAS and RAID can reach intense temperatures. WD Red Plus drives are designed and tested to perform under those extreme conditions.
  • 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.
