Management of storage space in solid state drives to support proof of space activities

An apparatus, comprising:

• a solid state drive, having:
• a host interface configured to receive commands from a host system;
• memory cells formed on at least one integrated circuit die;
• and
• a processing device configured to control executions of the commands;
• wherein the solid state drive has firmware configured to:
• allocate, in response to a first command from the host system, first storage resources of the memory cells to a host allocated storage space during execution of the first command;
• identify free storage resources available in the memory cells;
• allocate, from the free storage resources, second storage resources of the memory cells to store one or more proof of space plots;
• receive, from the host system via the host interface, a second command unrelated to proof of space activities;
• and
• allocate at least a portion of the second storage resources for execution of the second command.

A non-transitory computer readable storage medium storing instructions which, when executed in a memory sub-system, causes the memory sub-system to perform a method, comprising:

• allocating, in response to a first command from a host system connected to a host interface of the memory sub-system, first storage resources in the memory sub-system to a first namespace during execution of the first command;
• identifying, by the memory sub-system, free storage resources available in the memory sub-system;
• generating, by the memory sub-system in response to a determination that the free storage resources is sufficient to store a proof of space plot, a third command to create a second namespace;
• allocating, from the free storage resources, second storage resources to the second namespace to store the proof of space plot;
• and
• in response to a second command from the host system independent of proof of space activities:
• deleting the second namespace;
• and
• reallocating, at least a portion of the second storage resources for execution of the second command.
