Ok, so I built a desktop and didn't have a hard drive to use, so I decided to use my old xbox 360 hard drive. Turns out that the xbox hard drive is crap and is only SATA1, 5400RPM with 8MB buffer. I just ordered a new hard drive that is 500GB, SATA3, 7200RPM with 16MB buffer. I have bad loading times with my current hard drive and was hoping there is a big difference between the two hard drive, anyone care to clarify if there is a big difference?
