I have an HP chromebook running Ubuntu via Crouton, because it only has 16gb (11ish usable) I am looking to increase my storage capacity for music, games, documents, etc I also will probably have a couple of programs installed on it as well. Would it work ok? I would be doing regular backups onto an external 3tb drive, Would it be better to use a 128gb usb 3.0 flashdrive, or to use a 128gb SD card? I am thinking that the usb drive will be faster.
