The drive for NAS

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

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.


Desktop drives aren't purpose-built for NAS. But WD Red drives with NASware 3.0 are. Our exclusive technology takes the guesswork out of selecting a drive. We can help you find the perfect storage for your NAS system.

It's a hard drive. You fit it, partition it, format it and store data. Magic! I'm using it in a Raid 1 array. So far, so good.

The only reason that I can't give 5 stars is that the longevity of this product is what is important to me and I can't comment on that until it has been running for at least 5 years.
