Storage expansion card only works on Framework Laptop?

[Fraoch]

Yes. It’s a normal (fast) flash drive in an unusual form factor.

Do Framework's first party storage expansion cards act as flashdrives?

If I wanted to get data off my machine, Could I save what I wanted to an expansion card, take it out, and put it in any computer with normal USB C? seems like it would be neat to essentially have a 256 GB flashdrive with me at all times
