M.2 SSD Enclosure USB C to NVMe PCI Express

[Adamsavage79]

I'm just wondering, if I used a USB C NVMe PCI Express External drive, and plugged it into a Thunderbolt 3 port, would I get USB 3.1 speeds, or Thunderbolt 3 speeds ? I know USB C cords will work on Thunderbolt 3, but not the other way around.

Example being this: UGREEN M.2 SSD Enclosure USB C to NVMe PCI Express Adapter Aluminum USB 3.1 Type C Gen 2 10Gbps to M-Key Hard Drive Caddy External Case for 2230/2242/2260/2280 Support UASP, Tool-Free: Amazon.ca: Electronics

I suspect you are limited to USB 3.1 Gen 2 speeds (or whatever specs are given for the specific enclosure). For example, that enclosure seems to be limited to USB 3.1 Gen 2:
