Detailed description：I bought a 2TB nveme external sandisk extreme pro with claims that the read/write can go until 2000 mp/s. I tried in many way to get that speed and after searching for info on Google, this sandisk model needs a usb 3.2 gen 2. Before buying that, I checked that my zenbook duo 14 pro ux8402ze has that usb 3.2 gen 2. But the speed test is limited only around 1000 mps.
How can I solve this problem?
Ports specification of UX8402
1x USB 3.2 Gen 2 Type-A
2x Thunderbolt™ 4 supports display / power delivery
1x HDMI 2.1 FRL
1x 3.5mm Combo Audio Jack
1x DC-in
Micro SD Express 7.1 card reader

From the attached picture, I have tried to find out what gen of the USB 3.2. But I cannot determine if it is gen 2 or not. For now, I connect my 2TB sandisk extreme pro directly to the USB port type A (for my model, only this port). Sandisk continue to read and write only as a 1000 mb/s... not a 2000 mb/s one.
Please help...

Are you connecting this USB?
Could you please take a picture of how your laptop is connected to an external device?
Sorry for any inconvenience it may be caused.

Sandisk extreme Pro v2 is for USB 3.2 gen 2x2!
I don't know which brand provides this port until now.
I did forget to check for the port connection. I presumed that my UX8402 with 2 thunderbolt 4 ports must work with this external drive!

I found connection info of sandisk extreme pro v2 as the above.
My question is how to know if my UX8402ZE USB port is 3.2 Gen 2x2?...
