So as you may have read I’m now using a 128GB SSD. I’ve allocated 87.4GB of that space to Windows 7, which I’ve secured with EMET (DEP Always On, SEHOP Opt Out, ASLR Always On).
The vast majority of this space is going towards games. Borderlands is a full 21GB (don’t ask, special version) and Skyrim is another 7GB or so.
I have another 40GB of space for my Windwos partition and about 25GB for Ubuntu. Plenty. I could fit a whole other OS on here.
