I had Windows 10, GTA V and War Thunder on my SSD that was a 256 and still had room for various testing programs, montoring programs, a few hundred hi res pics taken with my phone and stand alone camera. With all of that I still had 22 gigs free on my SSD and it did not slow it down enough for me to notice. Personally games on an SSD is only an advantage on load times and honestly if you have a decent 7200 hdd its really not worth over loading your SSD for a few seconds on a game load.
