Abstract
A storage system is described that includes a controller and a disk array. The disk array includes at least a first and a second storage area. The first storage area is associated with a first mean time to failure (MTTF) and the second storage area is associated with a second MTTF. The controller operates to test the first storage area at a first frequency and the second storage area at a second frequency. The first frequency and the second frequency are each based upon the first and second MTTF so as to optimize the overall reliability of the storage system.
