Looking for a Hard Drive for my games

[fatalaeon]

I currently have a ssd and a 500gb WD caviar black installed in my pc. With the steam sales im quickly filling up my 500 gb hard drive, what are the specs im really lookin for here. I have alot of games (like 30 newer games) so im lookin at 2tb so i dont fill it up, but do i really need another caviar black or could i go with a little slower one for the games? will i notice it?

Caviar blue would be a good choice if you want to save some money.
