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.

NASware 3.0 Technology

Built for NAS Compatibility
WD Red Pro hard drives also have NASware technology and are purpose-built to balance performance and reliability in larger NAS and RAID environments.

LARGER NAS BAY SHOCK PROTECTION
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.
