I am considering purchasing a used PS4 Pro off of eBay. After receiving it, I will install a 4TB SSD. Currently, I play a few games when I go to a buddy of mine's house such as Quake II. Are there any major improvements on PS4 Pro when compared to a regular PS4? I know the games will run faster and there is an extra USB Type-A port. I hear 6 gigabit SATA connections are possible, but I am unsure if this is true.
