Prioritizing memory devices to replace based on namespace health

A computing device comprising:

• an interface configured to interface and communicate with a dispersed or distributed storage network (DSN);
• memory that stores operational instructions;
• and
• processing circuitry operably coupled to the interface and to the memory, wherein the processing circuitry is configured to execute the operational instructions to:
• based on detection of one or more EDS errors associated with one or more memory errors associated with a plurality of sets of memory devices of one or more sets of storage units (SUs) within the DSN that distributedly store a set of encoded data slices (EDSs) and for each corresponding set of the plurality of sets of memory devices of the one or more sets of SUs within the DSN, wherein a data object is segmented into a plurality of data segments, wherein a data segment of the plurality of data segments is dispersed error encoded in accordance with dispersed error encoding parameters to produce the set of EDSs:
• establish a corresponding memory replacement priority level for at least one corresponding memory device of a corresponding set of the plurality of sets of memory devices that is associated with the one or more EDS errors;
• and
• facilitate replacement of the at least one corresponding memory device of the corresponding set of the plurality of sets of memory devices that is associated with the one or more EDS errors based on the corresponding memory replacement priority level.
