When I bought my Xbox I was short on money so I had to buy a pathetic 20GB hard drive with it. I could only install one game at a time, what about DLC? Haha funny. Well I got it, transferred all my saves/content and everything works great; I've had 0 problems with it so far. With around 230 slots at your disposal, it will be difficult for you to fill all the available space. I have all my games installed on it and many of them (Mass Effect 2, Final Fantasy XIII) consist of two or more discs and I like Game of The Year Editions which have additional discs with bonus content (Borderlands, Fallout 3). all this is on this disk. Hell, I even bought Dead Space on Xbox Live (though I'll never do that again because it takes oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo to load). Oh, and this hard drive also comes preloaded with several demo games, including the absolutely amazing Geometry Wars.
