Ok. This might be a silly question since i know very little about RAID but I'll ask anyway. I've heard that RAID can be used to make two identical hard drives work together as one, thus delivering faster performance. I have also noticed a RAID section in the OSX Disk Utility. What exactly does that do? Is it a software RAID controller that could enable you to plug two identical ATA drives to the hard drive bus (I have an AGP graphics G4 450MHZ) and use them as one? Please tell me it is! Any help would be very nice.
