Can I use an external hard disk connected through Thunderbolt 4?

Dear Qubes community,

I have a Thunderbolt 4 USB C interface, but I haven’t yet bought an external hard disk that I could use to exploit this speed advantage. So first of all, is it possible to connect a hard disk via Thunderbolt USB C and use it in Qubes 4.2 as normal? In the sys-net settings, a usb and a thunderbolt device are displayed.

Yes. There could be some hardware-specific issues but at least it works for me.
