This will be my first system with RAID. I would like to transfer more data from permanant storage to RAM in less time [RAID 0]. I have researched some drives and am not sure which ones to get. I thought the 10,000rpm WD Raptors were the fastest SATA drives. Then I read a confusing article here about how Maxtor DiamondMax 10 7,200rpm drives with NCQ were faster in RAID 0 than the Raptors even though they spin slower. It seemed that they were compairing 3 DiamondMax 10 hard drives to only 2 Raptors. So I am asking what drives would you buy for the fastest two drive RAID 0 setup [not SCSI]?
