Oh, the stick is how I did it. It’s definitely great for the Test drive.
In my specific situation, I had A lot of files I wanted to move from the window system to the Linux system, and at that point in time, I did not have an external that had enough room to put them all on. I was also unsure if everything I needed would be compatible, so I wanted to save the windows SSD to be able to use as an external and boot from if needed. That did not end up being necessary, but I did plug it in as an external in order to recover some of those files that I wasn’t able to move to an existing external (mostly my ROM library and all my saves tbh, lmao)
