I have two reasons to ask this:
1-I don't want my Xbox360 fat model sounding like an aircraft constantly because she is reading the second disk
2-Xbox 360 20gb hard drive has about 13gb free of space: 8gb (If it's gonna be 8gb exactly) + 6,7gb like other games: 14,7
But I can install two games normally, for example RDR and EFLC, each one ocuppied 6,7gb. My possible solution is buy a new HDD (no) or buy an external hard drive (more interesting for me)
What do you think?
Hope people understand my english.
