Experienced in NAS
With superior technology that is driven to impress, WD Red is a reflection of the most extensive NAS partner compatibility-testing list that is available on the market.* That means when you buy a NAS enclosure, you can trust that WD Red will be the most compatible drive available.

Exclusive NASware 2.0 technology
Our exclusive technology, NASware 2.0, makes WD Red thrive in the demanding small-NAS environment. By adding WD Red to your NAS system, not only is everything more efficient and reliable, you can better protect your data investment.
3D Active Balance Plus
Our 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. (EFRX models only)

Advanced firmware technology built into every WD Red drive, NASware 2.0 enables seamless integration, robust data protection and optimal performance for systems operating in NAS and RAID environments.
