In a similar vein, I had an old MacBook Pro 2011 model. Its SATA chipset would negotiate SATA III speeds but any disk I/O at that speed would soon lead to widespread data corruption. SATA II drives and slower would be fine: no corruption. The funny thing was that this wasn't an issue when I used earlier versions of macOS: the problem only seemed to manifest when I "upgraded" to Mojave (IIRC). I surmised that maybe at that time period, whatever quirks or workarounds in the earlier OS versions no longer applied, and so whatever had caused the SATA III replacement drive to work (e.g., by force-negotiating at the slower speed) no longer did. :-( So, maybe a quirk/workaround that is in Linux and Windows but not in FreeBSD for you hardware *might* be a possibility?
