1. A method for execution by a computing device of a dispersed storage network (DSN), the method comprises: identifying an independent data object of a plurality of independent data objects for retrieval from DSN memory of the DSN, wherein the plurality of independent data objects is combined to produce a concatenated data object and wherein the concatenated data object is encoded in accordance with a dispersed storage error encoding function to produce a set of encoded data slices; determining a mapping of the plurality of independent data objects into a data matrix, wherein the mapping is in accordance with the dispersed storage error encoding function; identifying, based on the mapping, an encoded data slice of the set of encoded data slices corresponding to the independent data object; sending a retrieval request to a storage unit of the DSN memory regarding the encoded data slice; and when the encoded data slice is received, decoding the encoding data slice in accordance with the dispersed storage error encoding function and the mapping to reproduce the independent data object.
