For G4 Quicksilver; I'm looking for a fast small working drive setup that I can run internally and back up to a larger slower maindrive often. So cost aside (small capacity 36 GB drives), is there enough speed gained by the raid 0 with the two 10k drives to overcome the speed of a single 15k drive. These would be SCSI 320 drives running from a dual channel controller for the raid or single channel for the single. By speed I mean aprox. 50/50 read and write combination. I want to stick with this computer. Thanks
