Abstract: A processing system of a storage network operates by receiving a write request associated with a data object; identifying dispersed storage error encoding parameters; and determining a number of available storage units. When the number of available storage units is determined to exceed a first number, the processing system operates by: determining a first write threshold number in accordance with the dispersed storage error encoding parameters; dispersed error encoding the data object to produce a first write threshold number of encoded data slices; and writing, to available storage units, the first write threshold number of encoded data slices. When the number of available storage units is determined to not exceed the first number, the processing system operates by: determining a second write threshold number in accordance with the dispersed storage error encoding parameters associated, wherein the second write threshold number is less than the first write threshold number; dispersed error encoding the data object to produce a second write threshold number of encoded data slices; and writing, to the available storage units, the second write threshold number of encoded data slices.
