The Western Digital WD60EFZX belongs to the “red” series of WD RED disks that are specially designed for operation with small and medium NAS systems (Home & small office). It incorporates WD’s proprietary technology, NASware., Which makes the drives in this series suitable for the requirements of a small NAS system.
WD RED hard drives are specifically designed for optimum performance and reliability on a NAS array of RAID arrays. In contrast, desktop hard drives seem like an affordable alternative, but have a higher risk of potential data loss and failure of a continuously operating RAID array.
Compatibility: WD REDs are tested for compatibility with NAS systems. Desktop disks can have problems while completing the creation of a RAID array.
Reliability: WD RED disks are completely reliable, and no desktop disk is designed for the high operating temperatures or 24×7 operating conditions that a NAS requires. Thus WD RED disks are the most reliable solution when used in such a system.
Error recovery check: This series of disks has “smart error recovery”, while desktop disks are not designed for RAID environments and have built-in controls in their software (firmware), which prevent the RAID controller from helping. An error will cause the RAID array to fail, which will result in a disk or discs being discarded for a long time. Recovery then often takes several hours and can have significant effects on downtime on productivity.
Noise and Vibration: WD RED drives are optimized for multi-disk systems, which display higher levels of noise and vibration. If we use desktop disks in a NAS, then the additional vibration can reduce the life and reliability of the unit.
