Taken from B3D forums. Website is anonymous for obvious reasons, as this pic shows the file sizes for various 360 .iso's rar'd. OP also claims that unrar'd will add ~1-2GB, but I think that's way overstating it, as IME rar'ing does little in the way of saving space, and is more useful for easier torrenting than anything.
If I remember correctly, 360 discs have ~7GB of space available after the security stuff is added. These numbers, if true, are running quite close to limit especially considering they are first gen. Thoughts?
