(adsbygoogle = window.adsbygoogle || []).push({}); So I already ahve a PS3, but Halo Reach is coming out and a lot of my friends have XBox, so I think I'm getting an XBox aswell.

I don't really want to spend £200 on a 250GB, but would the cheaper 4GB model be big enough?

I've almost used the 60GB on my PS3, but idk if XBox files are smaller and such.

So how long would 4GB last?

If you plan on downloading a lot of DLC like map packs and such, you will want the larger hard drive. DLC can exceed 1GB in size and there can be multiple DLC's per game along with the normal game save data, so 4GB could fill up very quickly depending on how you use your console.

sounds u pro player who will make its hard drive full in short time

get 250G
