Hello I have a XPS 8950 bought two weeks ago. The problem is that I cannot get a transfer rate higher than 150/200 MB/s on any of the various usb ports (usb 3.2 gen1, usb C 3.2 gen 2 and usb C  3.2 gen 2x2). I'm doing the tests with a Crucial ssd nvme stick, and a cable rated at 20 Gb/s. These devices are working well since with the same ssd, the same cable and the same test files, i'm getting a transfer rate of 800 MB/s on the 3.1 usb port of my Asus laptop ! (which is normal for a working 3.1 usb port) What is the solution ? Thanks for your help.
