I checked their cables and they do sell a Pro cable on their website, which supports USB 3.0 Gen 2 speeds (10Gbps). I've actually been considering USB4 cables to eliminate the possibility of cables hindering the connection. But at the prices I've seen, I think I will be considering Gen 2x2 cables first.
@subbytna owns a company called Subbytech which also sells USB C cables. He very generously sent me a cable (and some Haribo) to test earlier this year. Although it only supported speeds on 480Mbps, it was a very good quality cable and I still use it now. He is expecting 20Gbps (Gen 2x2?) cables very soon and I've offered to buy one from him to test it out. When I do order the cable, I will re-order the above Sabrent NVME enclosure again for testing.
Yep 2m and 3m samples of USB C to USB C 3.2 gen2 20Gbps cables being sent to me this week.
