I would agree that going from a Amiga 3640@25MHz to a 060@50MHz with local memory and SCSI Controller makes a HUGE difference.
Would also say, going from a Warp Engine 040@40MHz with local memory and SCSI to a CS MK III is faster. If you compare to a CS MK I or II without SCSI, the Warp Engine it is give and take. For math the 060 is faster, for general usage the WE is faster (Since the WE has faster memory access then the MK II).
So I have the CS MK I, but no SCSI module. Quite frankly, SCSI is too loud.

My next upgrade down the road is probably going to be a FastATA and switch over to using CF cards. I also wish I could get a CD or DVD rom that isn't as loud or as long as the one I currently have. By Long, I mean if I could get one that is a couple inches shorter, I would have that much more room for cable management and air flow!
Any recommendations on a replacement CD-ROM?
