wherein the at least one processor is configured to:
receive information indicating cache loss from the storage device after device reset of the storage device,
suspend a data input/output operation for the storage device in response to the information indicating cache loss,
transmit a buffer read command to the storage device, and
receive, from the storage device, cache information related to data remaining in the cache without being stored in the non-volatile memory before the device reset, based on the buffer read command.
