Picked up my late 2012 Mini from the shop today, where I had the original HD swapped out for a new Crucial 2TB SSD. Also, the 10GB RAM was maxed out to 16.
I ran a CCC backup to the 2TB USB drive I've been using just before I took it in. A shade over 33 minutes. I just ran CCC again with the new setup. Same backup drive. 4 minutes, 52 seconds
