That SSD seemed healthy in every other respect and it's still chugging along today just fine. On ZFS no less. The kicker in the catastrophic failure was that none of the recovery tools worked and I'd need to write my own recovery tools to fill in the gaps where the metadata got corrupted. I also did not have much time to faff about - I imaged the disk and reinstalled the machine. As for the metadata, I was under the impression that there were no checksums for metadata in BTRFS?
