*Compatibility list as of March 2016
- Compatibility: Without being tested for compatibility with your NAS system, optimum performance is not guaranteed.
- Reliability: The always-on environment of a NAS or RAID is a hot one. And desktop drives aren't typically designed and tested in those conditions. WD Red is.
- Error recovery Controls: WD Red NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. Desktop drives are typically not designed for RAID environments where this can be an issue.
- Noise and Vibration Protection: Designed to operate solo, desktop drives offer little or no protection from the noise and vibration faced in a multi-drive system. WD Red drives are designed for multi-bay NAS systems.
