So it may be that the reason you no longer had errors in config 2 is
not because you put a different SSD in the 1st slot, but because you
now have the 2nd slot also occupied, like me.

If yours behaves like mine, I'd expect that if you swap the disks in
config 2, that you won't have any errors as well...
I'm very curious to see the result of that test!

Just to recap the results of my tests:

Setup 1
Main slot: Solidigm
Secondary slot: (empty)
Result: BAD - corruption happens

Setup 2
Main slot: (empty)
Secondary slot: Solidigm
Result: GOOD - no corruption

Setup 3
Main slot: WD
Secondary slot: (empty)
Result: BAD - corruption happens

Setup 4
Main slot: WD
Secondary slot: Solidigm
Result: GOOD - no corruption (on either disk)

So, in my case, it looks like the corruption only happens if I have
only 1 disk installed in the main slot and the secondary slot is
empty.
If I have the two slots occupied or only the secondary slot occupied,
there are no more errors.
