RAID 5 rebuild times on SSD?

Are there any benchmark metrics or technical details available about rebuild times when using RAID 5 on TLC FLASH 3 for the larger 1.8TB or 3.2TB drives? We're trying to determine whether to go with the default RAID 5 (8+1) or (4+1) for an all flash Unity.

We also do support RAID6 if you are concerned about exposure during rebuild

Lower quality SSDs at a heavy load lose speed, better not, this is important in restore time.

RAID 5 from 8+1 ???

just for clarity - These are NOT the drives models that Unity uses
