I have an RPi4 running ITS. I attached a fast USB3 memory rather than

But then it turned out not to be the load at all. No matter what I ran
on that Pi, it would corrupt its SD cards in a matter of weeks (the
symptom was that the fourth bit of some bytes would just stick on). I
assume it was just something broken in the Pi itself.
You can simply root off of a
