The drive for NAS

Desktop drives aren’t typically tested or designed for the rigors of a NAS system. Do right by your NAS and choose the drive with an array of features to help preserve your data and maintain optimum performance.

WD Red drives with NASware 3.0 technology are purpose-built to balance performance and reliability in NAS and RAID environments.

Keep it Cool

The always-on environment of a NAS or RAID is a hot one. WD Red drives are engineered to run cool and quiet while offering optimum compatibility for demanding 24x7 environments.


A desktop hard drive is not typically tested or designed for a Network Attached Storage device or RAID environment. Choose a drive that has been tested in NAS environments with an array of features to preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:

  • Compatibility: Without being tested for compatibility with your NAS system, optimum performance and reliability are not guaranteed.
  • Reliability: The always-on environment of a NAS or RAID can lead to increased tempratures, and desktop drives are not typically designed and tested in those conditions. WD Red drives are built for NAS.
  • Error recovery Controls: WD Red NAS hard drives are specifically designed with RAID error recovery control to help reduce fallouts with in the NAS system.  Desktop drives are not typically designed for RAID environments where this can be an issue.
  • Noise and Vibration Protection: Desktop drives are not typically tested or designed to account for the noise and vibration faced in a multi-drive system. WD Red drives are designed for multi-bay NAS systems with NASware technology to help prevent this.


Stream, backup, organize and effortlessly share your digital content to your TV, PC and more. NASware technology increases your drives' compatibility with your NAS system, for better playback with your devices.


Businesses thrive on productivity and efficiency, two guiding principles built into the design of the WD Red drive. Share and backup files at the speed of your business with a WD Red drive in your NAS.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second.
