Abstract
A method begins by a dispersed storage (DS) processing module determining that a plurality of sets of encoded data slices is to be stored in a set of storage units of a dispersed storage network (DSN) and identifying one or more devices of the DSN that will potentially issue a read request for at least some sets of encoded data slices. The method continues with the (DS) processing module determining transmission times between the one or more devices and the set of storage units and determining a storage strategy for storing the plurality of sets of encoded data slices in the set of storage units based on the transmission times and memory devices of the set of storage units such that, from set to set of encoded data slices, at least a threshold number of encoded data slices are retrievable with comparable read response times.
