Sadly the SSD does nothing when it comes to installing/downloading/updating games... Still takes forever and a day.
I actually keep all my games on 16 Terabyte Mechanical Drives and keep everything installed and updated in the background, I have always been a PC gamer, so we always had loading screens as our games tended to be larger and more complex than console variants even back in the Pre-Windows days.
It just doesn't bother me.
