The method includes: receiving a first command from the host device indicating a read operation of first status information of a first zone random write area (ZRWA) in a first zone region, wherein the first command complies with a zoned namespace (ZNS) standard; obtaining the first status information from a zone status table in the storage controller based on the first command, wherein the first status information indicates at least a portion of a first physical region of the non-volatile memory device corresponding to the first ZRWA in which first data are stored; and providing the first status information to the host device.
