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.

RAID 1 Sync | 0:41:10 | 17.29 W |

RAID 1 Rebuild | 0:52:05 | 16.15 W |

RAID 5 Sync | 0:44:04 | 22.23 W |

RAID 5 Rebuild | 0:42:18 | 20.54 W |

RAID 6 Sync | 0:13:42 | 28.19 W |

RAID 6 Rebuild | 0:20:38 | 24.63 W |

The RAID 6 sync and rebuilt periods are extremely short.
