Interesting. I was thinking failure to persist updates, inconsistent health check results, those types of nasty corner cases.

Sure. Premature optimization and all.

Huh. SSD from a major chip vendor perhaps? I had one of those bite me just a few weeks ago. in my case it would have been fine if the drive offlined itself. but the intermittent io pauses killed performance, but not health checks. Actually, same type of problem RO FSs make me scared of.
