Look at what striping does... It takes a number of drives and makes it appear that they are one large (faster) drive. Mirroring takes two drives of the same size and stores the information redundantly. Thus if you were to mirror a 4 drive combination to a single drive, that drive would have to be 4 times as large. It would also need to be fast.
