Abstract: A method, an apparatus, and a controller for managing a storage array that is divided into a first storage device subset and a second storage device subset according to degrees of wear of storage devices, where a minimum degree of wear of a storage device in the first storage device subset is greater than or equal to a maximum degree of wear of a storage device in the second storage device subset, and then, data in the second storage device subset is migrated to the first storage device subset or to-be-written data is written into the first storage device subset. Therefore, service lives of storage devices in the second storage device subset may be extended relatively by shortening service lives of storage devices in the first storage device subset.
