All other things being equal, multiple drives are certainly faster than a single drive. With two drives, you can make two accesses (almost?) simultaneously, whereas with one drive you have to wait for the read head to finish accessing the first file before it can move to read the second file. The more drives the better, provided you can split up your directory structure appropriately. You could even use ccd so that the filesystem is automatically and transparently split evenly between the disks, but that kinda puts all your eggs in one basket.
