Should i get a xbox 4gb or 250 gb?

In my opinon 250 because you can install your games onto it if your disk becomes unreadable(YOU NEED THE DISK NO MATTER WHAT TO PLAY) but tye disk wont spin keeping the heat to a minimal. If you dont with to do this, buy a 4gb and if you need a bit more space buy a flash drive (scandisk works) and google how to configure it. Its very easy.. You basically just plug it in then a few more steps. It doesnt have to be the microsoft flashdries so i reccoment scandisk because theyre prolly cheaper so yeah
