| My performance is lower than I expected. Does the drive order matter? | Nov-02-12 |
| In a 16-drive Fusion chassis, Sonnet formats, tests, and builds a RAID at the factory, then removes and numbers (as of Nov 2012) the drives for safe shipping. It is important to install the drives in the numbered order left-to-right. If you don't do this, the performance will suffer because the drive sequence gets scrambled through the SAS expanders to the RAID engine.
If you used the original RAID group built by Sonnet which did not have numbered drives or which numbered drives were not installed in sequential order, then back up your data, delete the RAID group and build a new RAID and your performance will improve.
This note does not apply to the DX800RAID. |

| Can I use Seagate Iron Wolf drives; or Hitchai and WD drives 8TB and larger? | May-31-18 |
| Some newer drives use a hole pattern different from the traditional drive hole pattern for the bottom mounting points. The location of the bottom holes close to the connector did not change; however, the bottom holes near the middle have been removed and replaced with bottom holes close to the front of the drive.
The drives with the new bottom hole pattern include:
Seagate Iron Wolf drives (also missing the middle hole from the side mount hole troika)
Hitachi drives 8TB and larger
WD drives 8TB and larger
Incompatible mount holes
Echo 15+ Dock (side mount, but needs middle hole, so incompatible with only Seagate Iron Wolf)
Fusion F3 (bottom mount)
Fusion D400Q/R400P/D500P (bottom mount)
Fusion D800/R800 (bottom mount)
Compatible mount holes
Fusion R400S RAID (side mount)
Fusion R400 RAID USB 3 (side mount)
Fusion DX800/RX1600 (side mount) If using Iron Wolf line, must use Iron Wolf Pro with rotational vibration sensors
