My current use case was caused by switching motherboard variants.
My latest plan focuses on the ASRock Rack ROMED8-2T, rather than the EPYCD8-2T. I’m not sure why, but they replaced the SATA-DOM port with a USB-C port + a 20-pin header.
sigh …there goes my boot/hypervisor option …which i really, really, really don’t want to run off of a non-smartctl-able dumb stick.
…so, yeah, a UASP-capable SATA adapter seems about right
