RAID Operations

We perform RAID sync operations during which we 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, we rebuild and sync RAID 1, RAID 5, and RAID 6 arrays, but are confined to a RAID 1 array in smaller two-bay NAS servers. The Bitmap option is disabled in NAS servers that support it to produce comparable results since it speeds up RAID rebuild times.

RAID syncing and building times are on the high side, which isn't surprising since the CPU isn't very strong.
