Right now I have a 200 gig western digital as my main hard drive. It has an 8 mb buffer I think. And its IDE. The best I can find in my research is that the transfer rate for IDE is 16 Mbs. And that SATA is like 3 gigs a second. Is that right, or am I looking at the wrong things. And if this is so, would getting one speed up my programs opening and what not considerably, or should I just worry about getting a raptor, and sacrificing storage space?
