Method of writing data in storage device and storage device performing the same

A storage device comprising:

• a plurality of nonvolatile memories;
• and
• a storage controller configured to:
• receive an identifier information request from a host device that external to the storage device,
• output information, to the host device, indicating a plurality of identifiers based on the identifier information request,
• receive, from the host device, a first write command comprising a first identifier among the plurality of identifiers and first data,
• perform a data write operation on the first data based on the first write command,
• receive, from the host device, a first attribute assignment command comprising the first identifier and a first attribute among a plurality of attributes, and
• assign the first attribute to the first data that is already stored in the storage device based on the first attribute assignment command,
• wherein the first attribute of the first data is not set while the data write operation for the first data is performed, and
• wherein the first attribute of the first data is set after the data write operation for the first data is completed and the first attribute assignment command is received.

A method of writing data in a storage device, the method comprising:

• receiving a first query request from a host device that is external to the storage device;
• outputting a maximum identifier number to the host device based on the first query request, the maximum identifier number representing a quantity of a plurality of identifiers that are used in the storage device to assign a plurality of attributes to a plurality of data;
• receiving a second query request from the host device;
• outputting an attribute determination expectation identifier list to the host device based on the second query request, the attribute determination expectation identifier list comprising the plurality of identifiers and information indicating whether each of the plurality of identifiers is available;
• receiving a first write command and first data from the host device, the first write command comprising a first identifier among the plurality of identifiers;
• performing a data write operation to store the first data into a first region of the storage device corresponding to a first logical address based on the first write command;
• recording the first logical address to an attribute determination expectation stream information list in association with the first identifier, the attribute determination expectation stream information list indicating a relationship between the plurality of identifiers and a plurality of logical addresses to which the plurality of identifiers are assigned;
• receiving a subsequent command from the host device, the subsequent command comprising the first identifier and a first attribute among the plurality of attributes;
• assigning the first attribute to the first data that is already stored in the storage device based on the subsequent command;
• and
• deleting the first logical address from the attribute determination expectation stream information list,
• wherein the first attribute of the first data is not set while the data write operation for the first data is performed,
• wherein the first attribute of the first data is set after the data write operation for the first data is completed and the subsequent command is received, and
• wherein the first identifier in the first write command indicates an attribute of the first data is scheduled to be set after the data write operation for the first data is completed.
