A method includes receiving a random order of encoded data slices, and de-randomizing the random order of encoded data slices to produce a plurality of sets of a transmit number of encoded data slices. The method further includes 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, the method further includes concurrently decoding 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 and combining the collection of data segments into the one or more data partitions. The method further includes combining the plurality of data partitions into the data object.
