But are there any performance advantages?
Is 250GB enough though once you've downloaded a few games/dlc/patches and installed a few off disc?
massively plenty. It's the biggest they do.
And now you have cloud storage for bits and bobs.
320gb (GOW3) is the biggest I beleive 'officially'.
I got a 4gb for £100, and got a 250gb for £30 seperately.
Exact same spec now as a 250gb console, except it's glossy and not matte.
No difference performance wise, and plenty of space.
