Synology DS420j 4-bay NAS Review
Output Noise »RAID Operations
I perform RAID sync 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 sync 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.| Synology DS420j | ||
|---|---|---|
| Operation | Time | AVG Power Consumption |
| RAID 1 Sync | 0:21:37 | 8.38 W |
| RAID 1 Rebuild | 0:24:36 | 8.53 W |
| RAID 5 Sync | 1:13:21 | 12.08 W |
| RAID 5 Rebuild | 0:36:07 | 10.78 W |
| RAID 6 Sync | 1:53:04 | 10.53 W |
| RAID 6 Rebuild | 0:54:07 | 10.99 W |
