WD Red Pro hard drives are designed specifically for medium or large business customers and are available for NAS systems with up to 24 drive bays. Designed for high-intensity workloads in 24x7 environments,
the WD Red Pro family is ideal for archiving and content sharing as well as building RAID arrays in advanced operating systems such as ZFS and other file systems. These drives increase efficiency by allowing your workers to quickly share files and reliably back up folders in your NAS solution.

Designed for optimal NAS compatibility - WD Red Pro hard drives with NASware technology make hard drive selection easy Our unique algorithm is optimized for NAS systems and ensures the right balance of performance and reliability in NAS and RAID environments. In short, WD Red Pro is the hard drive with the highest compatibility for NAS enclosures. That's backed by numbers. WD Red Pro hard drives are the result of extensive compatibility testing and extensive integration of technologies from our NAS partners.

Shock protection for drive bays in large NAS systems - WD Red Pro hard drives feature a multi-axis shock sensor that detects even minor impacts and dynamic head height adjustment that automatically compensates for shock during each read/write operation to protect your data. The combination of these technologies provides even greater protection for hard drives in large 24-bay NAS environments and increases the reliability of the drives.

3D Active Balance Plus - Advanced dual-level mass balancing technology significantly improves overall drive performance and reliability. Hard drives without proper mass balancing can cause excessive vibration and noise in a multi-drive system, reducing drive life and degrading performance over time.

Troubleshooting protection - Because WD Red Pro hard drives are designed specifically for RAID and NAS environments, they feature special troubleshooting mechanisms that are part of NASware 3.0 technology. This can significantly reduce hard drive failures in RAID systems.

Extensive disk testing - A NAS environment with up to 24 drive bays places a significant amount of stress on a hard drive in terms of increased vibration and heat generation. That's why every WD Red Pro hard drive undergoes extensive running-in tests with changing temperatures to ensure even greater reliability in operation.

Longer warranty coverage - WD Red Pro hard drives come with a 5-year warranty for added peace of mind.
