A:Answer I added a second SSD. A 1 TB drive. One major drawback was the fact that ASUS partition the C drive in such a way that it was hard to partition easily. On the question of how far it can go, meaning, how much memory you can add, depends on the operating system. And how you want to partition the drives depends on the skills and software tools you have. The good thing is that with two sockets, it will be easier to clone.
