Operating System
The WD Red family just got bigger

Our formula of success has led to the growth of WD Red into the highest capacities possible. Available up to 6 TB, WD offers an even broader, more comprehensive portfolio of NAS solutions for our customers spanning from a total of 1 to 16 bays. The WD Red family just got bigger.

NASware grows to 3.0

Built off of our determination to deliver the best NAS experience, NASware 3.0 extends our promise by further optimizing WD Red for the NAS environment with added support for 6 to 8 NAS bays. WD Red now supports small NAS systems from 1 to 8 bays thanks to NASware 3.0, which further improves drive compatibility and reliability. At 48 TB of total capacity in an 8 bay system, WD Red expands your NAS experience.

Professional solutions

Designed specifically with SMB customers in mind, the WD Red family has expanded with the addition of WD Red Pro, which is available for the 8 to 16 bay medium to large-scale NAS environments. With capacities up to 4 TB, WD Red Pro carries a 5-year limited warranty and was engineered to handle the increased workloads from your business.


Experienced in NAS

WD Red is a reflection of the most extensive NAS partner compatibility- testing list that is available on the market.* That means when you buy a NAS enclosure, you can trust that WD Red will be the most compatible drive available. Our pride is in our product and our vision is shared with our customers.
