If plugs a storage expansion card into a cell phone, will it work? And if put it on a different brand laptop, will it work?
Yes. It’s a normal (fast) flash drive in an unusual form factor.
I plugged a 1tB expansion card into a Galaxy Note 9. It wanted to format the device before use.
Didn’t do it, because I didn’t want to lose the data already on it.
But should work.
Same thing with a USB-A flash drive in the USB-A expansion care. The flash drive has a Fedora system on it.
