The InstaDMG guide suggests using separate drives for image creation to improve performance (i.e. one for reading the disk images and packages, one for the temp files and the output images). If I have am using a dedicated Mac mini (2009 server running 10.6 client) and an external FireWire 800 drive, what is going to give me the best performance? Drive to drive within the mini? Internal to FW 800 external? Internal RAID 0 to FW 800 External RAID 0? Forget the whole thing and just load up the internal drive bays of the Mac Pro (2006) that I use as my personal machine and have it work in the background? Experiences? Opinions?
