It was followed at 30 minutes later with a returned to normal. I’m hoping someone might have some idea what’s going on here? SMART report and diagnostics attached.

It's not that uncommon with some SSDs, e.g. Crucial MX500 and Transcend D370 have similar issues, just ignore or look for a firmware update.

Thanks. I’m surprised I haven’t seen this before. Been using this SSD for a while.

I've never seen it either, but I've never used those brands. The number is suspicious though, 1048576 = 2^20.
