I want to buy a new xbox 360 and be able to play backups. the BenQ drives are non-flashable/soft moddable (No Idea what the latter means?!) I don't want to buy one, and get a non-flashable drive and be stuck with the console. Are the majority a certain type? e.g. Hitatchi/Samsung? Are newer machines being shipped with certain drives? I'm in the UK if that helps?
