Abstract

A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN). The method begins by determining to recover a data object from one or more storage vaults of a plurality of storage vaults where the data object has been synchronously stored amongst the plurality of storage vaults. The method continues, for each storage vault, by determining a slice retrieval performance level and selecting two or more storage vaults of the plurality of storage vaults for retrieval based on the slice retrieval performance levels. The method continues by identifying a plurality of data segments for retrieval where the data object was divided into the plurality of data objects and assigning a storage vault for retrieval to produce assignment information and facilitating recovery of each data segment of the plurality of data segments from the selected two or more storage vaults.
