My connection to Comcast is only 400mbit or so. But I need a NAS, and most have 2.5gbe ports (Qnap, Asustor, etc). Just got a ryzen b550 motherboard, with 2.5gbe ports by default. I needed a new cable modem, which came with 2.5gbe ports by default. I do often move 20-40GB files around, so the bandwidth would actually be useful. Apparently ubuntu-20.04 has the right drives, but thanks for the info, seems like I might need to upgrade to a semi-current kernel to get the interfaces working.
