I got a new Seagate Barracuda 1TB for all my games a couple weeks ago and its a 3gbs HDD. I feel that when I was playing bf3 on my WD Caviar Green 6gbs HDD there was a difference in performance, like sorta a huge one. About 5-10 fps. I could understand how it could effect it but I wanna know forsure. Ive researched everywhere to see if there was something on this matter but couldnt find anything that was related to what I was looking for.
