1. A method for execution by a computing device of a dispersed storage network (DSN), the method comprises: receiving a random order of encoded data slices; de-randomizing the random order of encoded data slices to produce a plurality of sets of a transmit number of encoded data slices, wherein the transmit number is within a range of a decode threshold number and a total number; dividing the plurality of sets of transmit number of encoded data slices into collections of sets of the transmit number of encoded data slices; for a collection of sets of transmit number of encoded data slices of the collections of sets of the transmit number of encoded data slices: concurrently decoding, in accordance with a dispersed storage error encoding function, the sets of the transmit number of encoded data slices of the collection of sets of transmit number of encoded data slices to produce a collection of data segments, wherein the collection of data segments includes one or more data segments of a plurality of data segments from one or more data partitions of a plurality of data partitions of a data object; and combining the collection of data segments into the one or more data partitions; and combining the plurality of data partitions into the data object.
