By increasing NASware 3.0 capability, the WD Red 1-6 TB capacity drives are capable of supporting up to eight bay NAS systems.

Designed for medium to large business environments, the new WD Red Pro line of NAS hard drives supports eight to 16 bay NAS systems. The design offers high performance storage powered by NASware 3.0.
