A SSD versus HD wont make that much of a difference for this game outside of loading times, this is not a game that is a shooter or a platformer [assuming your having a modern HD and not one of those HP Pavilions from 10 years ago, at 3200 rpm- if you do your going to have a very very bad time.] Games mostly store calls in memory, as long as you have 16GB of Ram you should be fine ... if not try to reduce page file limit in your system. DO NOT EVER INCREASE PAGE FILE LIMIT ON A HD, YOU WILL REGRET IT LOL.
