Abstract
A method begins by a processing module determining a retrieval threshold for retrieving a set of encoded data slices from a dispersed storage network (DSN), wherein the set of encoded data slices represents data encoded using a dispersed storage error encoding function having a pillar width of “n”, a decode threshold of “k”, and an encoding ratio of n−k>k and wherein the retrieval threshold is in accordance with the encoding ratio. The method continues with the processing module issuing data retrieval requests to the DSN for the set of encoded data slices and receiving encoded data slices of the set of encoded data slices to produce received encoded data slices. The method continues with the processing module decoding the received encoded data slices to recapture the data when a number of received encoded data slices compares favorably to the retrieval threshold.
