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.

RAID 5 Sync | 16:21 | 18.90 W |

RAID 6 Sync | 27:21 | 18.45 W |

As expected, the SSDs provide a huge speed boost in these tests.
