I know at least in the old days with PCs that a PC will look for the boot drive in a certain sequential order, does the 2009 Mac Pro do that? I plan on installing a SSD boot in Bay 3 and will tell the OS that the boot is in Bay 3 but will the MP still look in sequential order, i.e. optical drive then Bay 1, Bay 2, etc., for the boot drive? I realize even if it did and my boot is in Bay 3 it would only slow down the startup process by at most a few seconds. I just want to optimize the setup. Any other issues affecting the speed of the startup process?? Slow vs. fast devices, device releases, and controller that can "talk" to multiple devices simultaneously. Thanks for any info. I guess this is an obscure question because I couldn't find anything when I did a search.
