Abstract: A method of operating a storage device which communicates with a host device includes allocating a plurality of unit zone regions each having a unit zone size, each of the plurality of unit zone regions being mapped to at least one corresponding memory blocks among a plurality of memory blocks in the storage device and supporting a sequential write in compliance with a zoned namespace (ZNS) standard, receiving a first request indicating an allocation operation of a first zoned namespace in compliance with the ZNS standard from the host device, determining a first mapping ratio by dividing a first zone size of the first zoned namespace by the unit zone size, based on the first request, and storing the first mapping ratio in a zone metadata table of the storage device.
