WD Red™ Pro NAS Hard Drive
- 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.
- Error Recovery Prevention - Built specifically for RAID and NAS environments, WD Red™ Pro drives come equipped with error recovery controls as part of NASware™ 3.0 technology to help reduce drive fallout in RAID applications.
- Extended Drive Testing - A NAS environment that has up to 24 bays is very demanding on a hard drive with added vibration and heat. This is why every WD Red™ Pro drive is shipped with extended thermal cycle burn-in testing to help ensure each drive is tested for extended reliable operation.
- 5-Year Limited-warranty - As an industry-leading hard drive manufacturer, Western Digital stands behind WD Red™ Pro drives for NAS with a 5-year limited warranty.
- Boost Your NAS - WD Red™ drives are available in capacities up to 22TB1 utilizing the OptiNAND™ technology’s capacity-enabling feature.
- Helps Protect Your Data - The innovative ArmorCache™ feature (22TB only) offers power loss protection of your data in write-cache enabled (WCE) mode while increasing performance in write-cache disabled mode.
