I know I'm suppose to use the SATA drive, , the fastest running drive to store the audio projects. But I don't know why. I don't know enough to tell the fellow who is building my computer. and the guy who is going to build the computer, is thinking that the 10000 RPM SATA drive should be used for the opperating system. Thinking that will make the computer faster I guess. Could someone explain it in a manner that he can understand why the audio drive, not the C drive needs to be the SATA drive? so we can build it that way with no reservations? Thanks for your input. http://www.gbrayton.com http://www.myspace.com/gbrayton http://www.sonicbids.com/GregBrayton
