This drive also features high levels of reliability, with 600,000 load/unload cycles, <1 in 1014Ā non-recoverable read errors per bits read, error recovery controls, and 1,000,000 hours MTBF for 1-8 bay NAS systems. Also built into this drive are noise and vibration protection and WD’s NASware 3.0 helps increase system compatibility, allowing WD Red drives to be more easily integrated with your existing network infrastructure.
- Compatibility: Without being tested for compatibility with your NAS system, improved performance is not guaranteed
- Reliability: The always-on environment of a NAS or RAID is a hot one and desktop drives aren’t typically 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 not typically 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
