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, while in smaller two-bay NAS servers, we are confined to a RAID 1 array. The Bitmap option is disabled in NAS servers that support it to produce comparable results since it speeds up RAID rebuild times.

Asustor AS6208T
Operation	Time	AVG Power Consumption
RAID 1 Sync	1:13	34.18 W
RAID 1 Rebuild	1:12	34.62 W
RAID 5 Sync	3:03	44.77 W
RAID 5 Rebuild	1:13	48.73 W
RAID 6 Sync	3:05	45.48 W
RAID 6 Rebuild	2:25	44.37 W
RAID 5 Sync (8x HDDs)	5:13	66.09 W
RAID 5 Rebuild (8x HDDs)	2:11	70.11 W
RAID 6 Sync (8x HDDs)	5:11	67.23 W
RAID 6 Rebuild (8x HDDs)	4:04	68.52 W

Syncing and rebuilding times are low compared to other NAS servers we have evaluated in the past. As you will notice in the table above, with eight HDDs installed, the sync time is much longer than with four HDDs, and the same applies to how much power is consumed.
