I want to use a sequencer and Gold on the same computer. I currently have one WD Raptor 36GB and I also have a WD 7200RPM drive.

What harddrive should I use for system apps and why? I read that some like the Raptor as the actual system(OS drive) yet I read that the raptor is best suited for streaming?

What could you suggest me as far as setting myself up for best performance?

Should I dedicate two raptors(buy one more) in Raid and use the 7200RPM drive for OS and get another 7200RPM drive to record the audio too?

How is your system set up. Do you use the same harddrives for streaming to write to?

Configure me the best harddrive setup in one computer.

I would appreciate it.
