I was just about to buy the same IBM 60GB HD I currently have (Deskstar 60GXP), to make a raid 0 setup with a new Abit Kt7Raid motherboard I purchased. But, there is a new model on Newegg, the Deskstar 120GXP. Should I purchase this 60GB HD instead, or stick with the identical one? Also, any advantages to the 120GXP? Thanks....
