i have a WD raptor atm, is very nice and fast but is limited by its small size of 37gig so ia going to get another 1 and set it up in raid 0 so the pc reads them as 1 drive. problem is my mate has told me that this will be a waste of time and you will not get any performance gains, yet i see alot of ppl are doing this? what dou you think? is it worth doing? i mainly use my pc for gaming. any comments welcom.
