TrueNAS used to be designed to boot off of smaller SataDOMs that were used only for boot. They were effectively WORM. At least, it used to be a few years ago. Everything that was written for the server was either a RAM disk or spread out amongst the RAID drives (as a separate partition, which has its own issues, but still). I had assumed this is what he was using the TLC SSD for. If that’s the case, so long as there isn’t much writing to it, it should be fine.
