This fixed the disk corruption errors at the cost of dramatically
reducing performance. (I'm not sure why because manual fstrim didn't
improve things)
That's interesting. I have quite a few of these drives and haven't
noticed any problems. What kernel version introduced the above
workarounds?
$ sudo lsblk -do NAME,MODEL

Looks like the fix was brand new around sept 2021

I was still seeing corruption in August 2022 but it's possible the fix
wasn't backported to whatever release I was running.
