Preference based selection of storage network memory for data storage

A computing device comprises:

• one or more interfaces;
• memory that stores operational instructions;
• and
• a processing module operably coupled to the one or more interfaces and the memory, wherein the processing module is configured to execute the operational instructions to:
• receive, via the one or more interfaces, a data object for storage in memory of a storage network;
• determine a system level storage efficiency preference associated with the data object;
• select a set of storage nodes of a plurality of sets of storage nodes for storage of the data object based, at least in part, on the system level storage efficiency preference;
• determine dispersed storage error encoding parameters for the data object;
• encode the data object in accordance with the dispersed storage error encoding parameters to produce encoded data slices;
• and
• generate system addressing information for the encoded data slices.

A non-transitory computer readable storage medium comprises:

• at least one memory section that stores operational instructions that, when executed by one or more processing modules of a computing device of a storage network, causes the computing device to:
• receive a data object for storage in memory of a storage network;
• determine a system level storage efficiency preference associated with the data object;
• select a set of storage nodes of a plurality of sets of storage nodes for storage of the data object based, at least in part, on the system level storage efficiency preference;
• determine dispersed storage error encoding parameters for the data object;
• encode the data object in accordance with the dispersed storage error encoding parameters to produce encoded data slices;
• and
• generate system addressing information for the encoded data slices.
