@K3Nv3, Yup, I was thinking of that because the super slims cannot have custom firmware installed, you can only do PS3HEN which is like a soft-mod of sorts but not permanent.
@BigOnYa, 1TB SSDs don't cost all that much nowadays, you should be good to go with one. Nothing too abysmal like 16TB as you're going to be using a small portion of that.
