Abstract
An apparatus with a solid state drive (SSD) configured to manage storage resources for proof of space activities. The SSD has a host interface configured to receive at least read commands and write commands from an external host system. The SSD has memory cells formed on at least one integrated circuit die, and a processing device configured to control executions of the read commands and the write commands. In response to an indication of a storage space request for the host system, the apparatus identifies an application using a proof of space plot stored in a portion of the solid state drive, requests the application to separate from the proof of space plot, and then delete a namespace in which the proof of space plot is stored to release storage resources occupied by the proof of space plot to meet the storage space request.
