Abstract
A method for use in a dispersed storage network (DSN) includes receiving a data access request at a DSN memory that controls storage of encoded data slices in multiple storage units. The data access request is capable of being serviced using either of at least two different storage units. The DSN memory determines wear levels associated with the two different storage units, and selects one of them as a preferred storage unit based, at least in part, on the wear levels. The DSN memory fulfills the data access request using the preferred storage unit.
