Product Features
For small or medium businesses: Stream, backup, share, and organize your digital content with a NAS and WD Red Plus drives designed to effortlessly share content with the devices at your home or business. NASware technology increases your drives' compatibility with your existing network and devices. For larger businesses with up to 24 bays, count on WD Red Pro drives to deliver exceptional performance.
Exclusive NASware: Not just any drive will do. Get a large capacity in your 8-bay NAS system and with Western Digital's exclusive NASware technology, you can optimize each and every drive. Built into every WD Red hard drive, NASware advanced technology improves storage performance by increasing compatibility, integration, upgradeability, and reliability.
WD Red Pro for big business: If you're looking for heavy-duty performance for NAS, WD Red Pro NAS hard drives deliver exceptional performance for medium to large business customers with extreme demands. For NAS environments with 9 to 24 bays, WD Red Pro drives deliver uncompromising performance.
3D active balance plus: The enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.
