and why Vertex 3? there's better drives out there around the same price range aren't there?
testifytheres an option in steam now for installing games to a different directory, use that.
Here's the Steam support page...link
Where is this "option"?
EDIT: oh guess it's only these limited games that have it...on steam beta atm?
You have to create a symbolic link/junctions, if you want to keep steam in the SSD and games elsewhere. There are tools out there that can make these for you.
