In case this hasn't been discussed elsewhere, running the game and the user game folder off of an SSD will stand to speed up startups/saves, foreign world travel transitions, CAS, Build/Buy and Pattern catalog building, and caching. The game doesn't really run any differently besides those things as most everything else is loaded into RAM and there is nothing faster than RAM access.
And sorry, I misunderstood. If you are running your operating system off of this SSD, it does need plenty of free space for itself and the game to manuever. Hopefully you still have at least 35 GB (more would be safer) of free space on it after the symlinking? For some reason I thought you had added an additional larger (more than 256 GB) SSD over and above what you already had and were just now populating it with things for it to do.
