Computing system and operating method thereof

A method of operating a computing system including a host and a storage device, the method comprising:

• providing a user with a first request including device setting inquiry information through a user interface;
• and
• setting a device configuration based on a first response to the device setting inquiry information acquired from the user through the user interface,
• wherein the device setting inquiry information includes at least one of information on allocation of a map buffer in a host memory, information on allocation of a write buffer in a buffer region of the storage device, or information on a power level of the storage device.

A computing system comprising:

• a host including a host memory and a user interface;
• and
• a storage device including a controller and a memory device,
• wherein the controller is configured to:
• generate device setting information;
• and
• provide the device setting information to the host,
• wherein the host is configured to:
• provide the device setting information through the user interface;
• acquire device setting response in response to the device setting information from the user through the user interface;
• and
• provide the device setting response to the controller, and
• wherein the controller is configured to:
• receive the device setting response from the host;
• change firmware code based on the device setting response;
• and
• transmit a device setting command based on the changed firmware code such that the memory device changes device configuration based on the device setting command, the device configuration associated with allocation of a buffer region of the memory device or a power level control of the memory device.
