Exclusive NASware 3.0 technology
Our exclusive advanced firmware technology, NASware 3.0 enables seamless integration, robust data protection and optimal performance for NAS systems operating under heavy demand.

Built for optimum NAS compatibility
Desktop drives aren't purpose-built for NAS. But WD Red Pro drives with NASware are. Our exclusive technology takes the guesswork out of selecting a drive and balances performance and reliability in NAS and RAID environments. Simply put, WD Red Pro is the most compatible drive available for medium to large NAS enclosures. But don't take our word for it. WD Red Pro is a reflection of the most extensive NAS partner compatibility-testing list that is available on the market.

Larger NAS Bay Shock Protection
WD Red Pro is equipped with a multi-axis shock sensor that automatically detects subtle shock events and dynamic fly height technology which adjusts each read-write function to compensate and protect the data. This combination of technology further protects the drives in larger 1 to 16 bay NAS environments and helps increase hard drive reliability.
