That's a clear indication that your issue is either linked to that disk or to that slot. The next step is to figure out which.
I suggest destroying RAID 1,2,5,6, and removing those disks. Then power down the NAS, and swap RAID 3 and RAID 4. Power up and re-run the test on both volumes. That will let you know if the problem is linked to the disk or the slot.
If the problem disappears on both disks, then it could be power-related. You can confirm that by adding the removed disks back one at a time, and see when the problem starts happening again.
I have partitioned jbod raid drives into each drive. RAID number 4 checksum error. But no errors in dmesg.
