1. A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method comprises: sending a set of low retention priority write requests to storage units of the DSN, wherein each low retention priority write request of the set of low retention priority write requests includes a low retention priority query; for each storage unit of the storage units that receives a low retention priority write request of the set of low retention priority write requests: determining a low retention priority response regarding availability for storing low retention priority data based on current storage of low priority data objects and available memory for storing the low retention priority data; and sending the low retention priority response; and when a threshold number of favorable low retention priority responses have been received, facilitating storage of a low retention priority data object.
