120gig Hard Drive,and Transfer Cable
Such a Huge difference to gaming on the 360.
Load the games to the Disc,and off you go,no Issues with potential Disc
scratching,and more importantly,seriously reduced noise.
Also to note,many other reviews I have read,suggest Games run smoother with the 120gig disc,seek times,cache increases etc.
If you are into 360 gaming,even,casual,like me,then,it's well worth getting the big drive
