The main difference is that Premium comes with a (20gb) hard drive and the Arcade comes with a little memory card . The hard drive separately costs 100 dollars (the difference between the two pakages) and I dont think the card will last long if you plan to download demos and arcade games.

A flash drive is a stick of memory that can be used to store and transfer information between different computers. It retains the contents of the memory chip even though there is no power. It was called Flash memory because when the memory is wiped it was likened to a flash from a camera.
