For up to 16 bay medium to large-scale NAS environments, the WD Red Pro drive is engineered to handle increased business workloads and carries a 5-year limited warranty. Add value to your business by enabling your employees to quickly and reliably sync their files and back up folders or share work with clients. Seamless integration, robust data protection and optimal performance for larger NAS systems that demand more. WD Red Pro hard drives also have NASware technology and are purpose-built to balance performance and reliability in larger NAS and RAID environments. A multi-axis shock sensor automatically detects subtle shock events that may occur in larger NAS environments and when combined with dynamic fly height technology, helps to adjust each read-write function to compensate for increased vibrations and protect data. Desktop drives aren't purpose-built for NAS. But WD Red Pro 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.
