500GB HDD or 320GB+120GB HDD?

Assuming it cost the same and all the drives are 7200rpm, would it improve game loading performance at all to put Windows on a separate 120GB HDD and use the 320GB HDD as my main drive? Or should I just go for the 500GB drive?

 
Solution
You should just use the one hard drive. There will not be any difference in performance. In fact, if you put windows on one drive and other programs on another, you could a little performance. Hard drives are supposed to have 10-15% free space and you'll probably end up having less space. I know the math says you'll have the same amount of space, but I doubt you'll be able to efficiently split files. And windows doesn't need 120gb. A 64gb drive would be more than enough. Also, if you haven't opened something that's installed on your larger, non-OS hard drive in a while, depending on the hard drive, it'll spin down and you'll have to wait for it to spin up again, causing things to "freeze" for a few seconds while the drive is spinning...
It would improve performance somewhat, since you can use both drives for virtual memory,or on the other hand, games should load faster since windows background processes would not be using any of the gamedrive's capabilities when loading a game.
