Status reporting for storage device

A persistent storage device, comprising:

• persistent memory;
• a processing circuit;
• and
• memory,
• the memory storing instructions, that, when executed by the processing circuit, cause the processing circuit to perform a method, the method comprising:
• receiving a command, the command requesting a status associated with a first logical block address;
• determining the status associated with the first logical block address;
• and
• sending a response to the command, the response comprising the status associated with the first logical block address,
• wherein:
• the status associated with the first logical block address comprises an unmapped status,
• the status associated with the first logical block address comprises a status of an allocation granularity,
• the allocation granularity is associated with a set of memory locations associated with a range of logical block addresses, and
• the range of logical block address includes the first logical block address.

A system, comprising:

• a host;
• and
• a persistent storage device, connected to the host,
• the host being configured to send, to the persistent storage device, a command, the command requesting a status associated with a first logical block address,
• the persistent storage device being configured, in response to receiving the command, to:
• determine the status associated with the first logical block address;
• and
• send a response to the command, the response comprising the status associated with the first logical block address,
• wherein:
• the status associated with the first logical block address comprises an unmapped status,
• the status associated with the first logical block address comprises a status of an allocation granularity,
• the allocation granularity is associated with a set of memory locations associated with a range of logical block addresses, and
• the range of logical block address includes the first logical block address.
