An apparatus and method for providing selectively redundant storage within a computer. The device comprises a first storage device having a first form factor and a first height, a second storage device having the first form factor and a second height, coupled to the first storage device, such that the first form factor, first height, and second height allow the first storage device and second storage device to fit within a standard cage of a computer, and a controller, coupled to the first and second storage device, for selectively storing data on the first storage device and the second storage device, wherein the controller interfaces to the computer and presents the first storage device and the second storage device as a single storage device to the computer. The method comprises coupling a first storage device to a computer through a controller, coupling a second storage device to the computer through the controller, such that the first storage device and the second storage device comprise a single storage device for the computer, storing data on the first storage device based on instructions received from the controller, and storing data on the second storage device based on instructions received from the controller.
