Did you read his post? He said to give results form version 6. A lot has changed between 6 and 7.

4K results look good, sequential reads look good (albeit limited with depth - hitting a wall), sequential writes are low. This is hitting both drives similarly? I actually found a bug on X570 with certain drives that can cause this, but only your SX8200 Pro would apply and only in the chipset (lower) M.2 socket. Check 4K alignment with the program "AS SSD" but also be aware that TLC write speeds for 500GB drives can get quite low (300-600 MB/s depending). Not that the drives should be hitting TLC, just that they are.
