program instructions to prioritize replacement of a second set of storage devices from among the first set of storage devices associated with the namespace of the user based on one or more factors;

program instructions to dictate to replace the first set of storage devices that store data corresponding to the namespace and are included among the one or more storage systems;

program instructions to determine whether a storage system affected by the first set of storage devices to replace includes one or more other storage devices that include a set of characteristics that are within a threshold level of the first set of storage devices to replace; and

program instruction to determine to replace the one or more other storage devices in addition to the first set of storage devices.

7. The computer program product of claim 6 , wherein the namespace is associated with a plurality of data and associated with the user.
