yea yuo can set it up when you install windows you press f6 i think, the drives should be the same (speed, size, interface ect), if you do a raid 0 then the data is split and sared betewwn the two drives, thid id risky cos if one drife fails you loose all the data as it is splip between the 2, other option is a raid 1 which is more relible as the data isnt split, but if you raid 1, 2 drives then you have the use of one drive (if ya see what i mean)
