I am thinking about getting a couple WD Raptor 74 gig SATA's (and putting them into RAID 0) in the next couple months and wanted to know some first hand advice. I have an Asus A7N8X-E Deluxe with an onboard Promise PDC20378 RAID controller. Anyone use that kind of config or simular? I currently have 2 160 gig Maxtors that are not in RAID. Will I notice a huge speed boost with the 2 Raptors? Any help would be greatly appreciated!
