SanDisk extremes (I picked the ones rated for good video with the idea that that needs more high-speed block writes than photos) are what I use. I just haven't tried to do something like a bonnie test with that vs a USB drive, or decided if that really mattered when your workload is a big obscene compile. [I have issues doing parallel builds without fails because you never know when two things are going to fight for memory and fail (it's basically unrepeatable random luck of the draw), and if you go into OOM-failure all kinds of random things get killed off. Having 48+ hour builds get wacked just sucks.] The llvm builds are bad, rust is bad. llvm is like 48 hours, and you end up with two of those these days if you're trying to compile firefox and then add rust which is even longer (~72 hours? I forget). RPI4 should be nice. The guy who was working on it on this list had made some good progress but doesn't look like he's had a lot of time past what he's done so far. I've been eyeing the pine64 boards myself. I think I could get into their product line. That particular board has what I was looking forward to in the RPI4. It looks like FreeBSD is trying to stick mainstream (64-bit vs 32) from some of the ARM support discussions I think I remember (admittedly they were trying to cut off some old ARM chips that happened to be 32-bit, so maybe just 32-bit isn't unforgivable, but 4+G of RAM on 32-bit would be an issue unless ARM has some kind of PAE.
