1. A method for execution by a processing system of a dispersed storage and task (DST) processing unit that includes a processor, the method comprises: determining first information dispersal algorithm (IDA) parameters; determining second IDA parameters; dividing data for storage to produce a plurality of first segments in accordance with the first IDA parameters and a plurality of second segments in accordance with the second IDA parameters; dispersed storage error encoding the plurality of first segments utilizing the first IDA parameters to produce sets of first encoded data slices; dispersed storage error encoding the plurality of second segments utilizing the second IDA parameters to produce sets of second encoded data slices; and facilitating storage of the sets of first encoded data slices and the sets of second encoded data slices in a plurality of storage units.
