I was wondering if it was possible to actually install a Linux distribution on an SD card or any other external drive. What I was planning to do was basically inserting the SD in my MacBook, turning it on pressing the Option key and choose the SD as boot source.
I am quite concerned by two issues: 1. Can this actually be done? I am aware this can be done on a partition of my hard drive, but I'm not sure about external drives. 2. What about the speed? Would it be too slow?
