If you're getting random corruption like that, you should replace the SSD. SSDs (and also hard drives) already have built-in ECC, so if you're getting errors on top, it not just random cosmic rays. It's your SSD being extra broken, and doesn't bode too well for the health of the SSD as a whole.

I bought a replacement but never bothered swapping it. The weird thing is the random corruption stopped happening a few years ago (confirmed against old backups, so it's not like I'm just not noticing).
