Abstract
An apparatus with a solid state drive (SSD) having firmware to manage spare 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 to retrieve data from the memory cells and executions the write commands to store data into the memory cells. The firmware is executable in the SSD to allocate storage resources not used or allocated by the host system to support proof of space activities and dynamically return the allocated storage resources when execution of a command from the host system needs additional storage resources.
