Typically what you want to do is have a SSD (doesn't even need to be bigger than 80gbs honestly) install your OS on it + a game/programs you want to load FAST, while everything else gets written to your other HDD (pictures, videos/pron, documents, blah blah blah). Then there's quite a few tweaks with folder structures and pathings I like to do to prevent anything writing to the SSD other than what I specifically tell to (also I tend to move my Page files to my HDD, simply because I have 20+ gb of RAM and disable Sleep/Hibernate). Your computer will Boot much faster, FFXIV and any other applications you install on it will run much faster... and you'll love life. SSD upgrades typically feel like upgrading your entire computer for the price of 1 component. Gratz!
