1. 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 a processing module operably coupled to the interface and to the memory, wherein the processing module, when operable within the computing device based on the operational instructions, is configured to: process monitor signals received from a plurality of sensors coupled to a plurality of biological memory devices (BMDs) within the DSN via a plurality of brain computer interfaces (BCIs) that respectively couple to the plurality of BMDs to determine status of the plurality of BMDs that distributedly store a set of encoded data slices (EDSs) associated with a data object, wherein the data object is segmented into a plurality of data segments, and wherein a data segment of the plurality of data segments is dispersed error encoded in accordance with dispersed error encoding parameters to produce a set of EDSs; service data access requests associated with the data object for at least some of the EDSs of the set of EDSs via the plurality of BCIs that respectively couple to the plurality of BMDs; when status of a first portion of a first biological memory device (BMD) of the plurality of BMDs compares unfavorably to a first threshold and compares favorably to a second threshold that is lower than the first threshold, transfer one or more EDSs of the set of EDSs stored in the first portion of the first BMD to a second portion of the first BMD that has status that compares favorably with the first threshold; and when status of the first portion of the first BMD of the plurality of BMDs compares unfavorably to the second threshold, perform a rebuild of the one or more EDSs of the set of EDSs stored in the first portion of the first BMD to generate rebuilt one or more EDSs of the set of EDSs and store the rebuilt one or more EDSs of the set of EDSs in the second portion of the first BMD that has status that compares favorably with the first threshold or within a second BMD that has status that compares favorably with the first threshold.
