What is the limit on how much bandwidth you can push through on this board?

Have you tried SCSI PCI cards? I am thinking CM4 will make a good platform for my old SCSI based SS4000 scanner!

I haven't tried a SCSI card yet; I just got in a batch of new cards to test, and I'll be sure to keep this site updated over time: https://pipci.jeffgeerling.com/

So far it seems like wired networking maxes out around 4.2 Gbps, but I haven't tested also using the USB 2.0 and built in WiFi to see if I can pump through even more bits.

I'm also planning on testing 10G (will probably max out at 3.2 Gbps) and a WiFi 802.11ac card.
