Sounds great, Massimo. I'm very happy with my Studio - and I only went with 32GB.
I've used 1.6TB of my 2TB SDD but 1.4TB of that is my Picture file with all my images - over 55k of them - collected since 2003. I'm starting to think about moving that file to an external SDD - or at least part of it.
If anyone has ideas for a SDD which is fast enough to enable online LR and PS editing, I'd be interested. I was thinking of the Sandisk Extreme Pro but, as a portable disk, I was wondering if it's not a bit too flimsy for a long-term external drive.
