Abstract: An operation method of a storage device configured to communicate with an external device through an interface channel includes receiving an indicator of a first throttling level of a plurality of throttling levels from the external device, setting a first operation parameter based on a throttling predefined table (PDT) including a relationship between the plurality of throttling levels and a plurality of throttling performances, such that the interface channel has a first throttling performance from among the plurality of throttling performances, the first throttling performance corresponding to the first throttling level, receiving a first input/output (I/O) request from the external device through the interface channel having the first throttling performance caused by the setting of the first operation parameter, and processing a first operation corresponding to the first I/O request through the interface channel having the first throttling performance.
