Abstract: Disclosed is a write method comprising a step in which a storage device determines an execution order between received first and second write commands, and executes the first write command and the second write command according to the determined execution order. The first write command comprises first stream identification information having {first stream ID, first epoch ID}, the second write command comprises second stream identification information having {second stream ID, second epoch ID}, and when the first stream ID and the second stream ID are different from each other, the execution order is determined without using the result of comparison between the first epoch ID and the second epoch ID.
