So I currently have a MBPR Mid 2012 that I am thinking about replacing for several reasons. Mainly GPU and CPU performance and the 1TB SSD. What I'm wondering is if I can run my Lightroom Catalog and files of the SSD efficiently. Yes, I understand that 1TB isn't a lot of space with apps and other files on my machine but I'd be willing to purge as much as possible to have the convenience of editing photos without an external USB 3 drive attached. Anyone see any problems with my logic or any angles I am missing?
