With new RTL8159-based 10G USB 3.2 adapters coming onto the market, the bulky adapters might be a thing of the past. Just look at the size of the thing in comparison to my Thunderbolt adapters: 2.5G and even 5G USB adapters have been out for a while, but sometimes you need more bandwidth. The 10G adapter I'm testing is this $80 model from WisdPi . That's double the price of most 5G/2.5G adapters, but less than half what I paid for my Thunderbolt 10G adapters.
