Abstract
A computer-implemented method and computer system for managing a group of storage devices in a storage system utilizes actual wear levels of the storage devices within the group of storage devices to sort the storage devices in an order. One of the storage devices is then selected as a target storage device based on wear level gaps between adjacent sorted storage devices using a target storage device wearing profile so that write operations from software processes are directed exclusively to the target storage device for a predefined period of time to control wear on the group of storage devices.
