US Patent 12120177 Performance based access in a storage network

A computing device includes an interface for communicating with a storage network and is configured to determine a performance level for each set of storage units of a plurality of sets storage units in the storage network, where the performance level includes a number of errors detected during a period of time T. The computing device is further configured to update performance information for the plurality of sets storage units to produce updated performance information for the plurality of sets storage units and determine which sets of storage units of the plurality of sets storage units meet a minimum performance level. The computing device is configured to receive a set of read requests for a set of encoded data slices stored on the plurality of sets storage units and transmit a threshold number of read requests of the set of read requests to a set of storage units that meet the minimum performance level.
