Folks, I know this isn't strickly proper to this forum however, as it's for my editing PC, and you guys are extremely knowledgeable I'm posting it here. What is the better spec'ed HDD, Ultra ATA133 or Serial ATA? I'm sticking in a second HDD as I'm experiencing dropped frames and having done everything else recommended on one of Mark's replys to this problem, seperate HDDs is the only thing left. I have noticed a considerable slow down of my system anyway since setting it up in October. I have defragged and tried to clean up the drives as much as possible, but it is still ugly and slow. I have the following: P4 3.2mhz HT technology 1gig RAM 250gig HDD (partitioned into 40gig/200gig) P4C800 deluxe motherboard 9800 ATI Radeon graphics card NEC 2510 DVD burner Sony DVD rom I do feel with these specs. I shouldn't experience dropped frames but do. with Sony Vegas being more unforegiving than other programs.
