I swapped out my power supply, changed ALL cables and bought a $1000 raid

SMART shows the same thing on many of the disks in the RAID10:
Error 1 occurred at disk power-on lifetime: 3708 hours (154 days + 12 hours)
When the command that caused the error occurred, the device was active or
idle.
I spoke to soon, turning off NCQ helped dramatically, it worked three times!

Then it crashed again, with NCQ enabled, it would not even complete one test,
So basically a new system, new PSU, new cables, its on a new APC UPS and the
problem persists even when all disks are on a RAID card, SW raid, it does not
matter, Velociraptors have problems, I think its time for me to get regular
1TiB disks and be done with it.
