Running FreeBSD on M.2 SSD

[Daniel Kalchev]

I have had disks, that work “perfectly" under UFS and various RAID controllers (and DOS and Windows), but always reported checksum errors when running under ZFS. It would happen on any motherboard or controller. That made me never use anything but ZFS on data that I cannot recreate 100%, fast… but that is separate story. I labeled those disks bad and they sit in my “museum”. Needless to say some were brand new. Not saying you have this issue, but sharing anecdotal evidence.

But I wonder how you discovered you had corruption with UFS? What is observed?

It might well be, that FreeBSD is more agressive with your motherboard/chipset or does not implement known quirk of that — which might trigger some edge cases for the SSD. Ultimately, if you can move that SSD to another motherboard and test it, it would confirm where the issue is.
