I have one Seagate (30 GBytes, ATA66, 7200RPM) and one Maxtor (30 Gbytes, ATA100, 7200RPM). Is it possible to have these two hard drives in a raid configuration? How about two hard drives with different size? How about two hard drives with different RPM? I am also think about buying a Maxtor 540X 40GBytes 5400RPM hard drive. Is the performance difference between a 7200RPM hard drive and a 5400RPM hard drive really warrants their price difference?
