I never needed more than the 32gb that came with it since I bought mostly physical games, but you could use a USB stick

are there any limitations / disadvantage of using USB stick?

Possibly, USB thumb drives are not designed to be constantly reading/writing/deleting files, so that could wear them out. Prehaps a usb SD card reader would be fine or a small external hard drive or solid state drive would be best.
