Determining a performance threshold for a write operation

A method for execution by one or more computing devices of a storage network, the method comprises:

• obtaining storage performance information for a set of storage units of the storage network, wherein the one or more computing devices dispersed storage error encodes data segments into pluralities of sets of encoded data slices in accordance with error encoding parameters, wherein the error encoding parameters include a pillar width number and a decode threshold number, and wherein the decode threshold number of encoded data slices of a set of encoded data slices of the pluralities of sets of encoded data slices is required to reconstruct a data segment of data segments;
• determining, based on the storage performance information and the error encoding parameters, a performance threshold number for a write request to store a set of encoded data slices of the pluralities of sets of encoded data slices in the set of storage units, wherein the performance threshold number is greater than the decode threshold number and less than the pillar width number;
• and
• executing the write request to store the set of encoded data slices in the set of storage units in accordance with the performance threshold number.
