Synology DS923+ 4-Bay NAS Review

Time to Boot & Restart - Output Noise »

RAID Operations

I perform RAID synchronization operations during which I measure the time the NAS needs to complete these tasks—average power consumption for these rebuild and synchronization periods is also measured. In NAS servers with four bays or more, I rebuild and synchronize RAID 1, RAID 5, and RAID 6 arrays, while in smaller two-bay NAS servers, I am confined to a RAID 1 array. The Bitmap option is disabled in NAS servers that support it to produce comparable results because it speeds up RAID rebuild times.

The RAID 6 sync and rebuilt periods are extremely short.
