Abstract: A storage device includes a multi-function controller configured to control a plurality of functions requested from a host, a power loss protection (PLP) capacitor configured to supply auxiliary power to the storage device, and a PLP controller configured to periodically monitor a status of the PLP capacitor and manage a performance list including pieces of performance information supportable for the plurality of functions according to the status of the PLP capacitor. The PLP controller is further configured to provide the performance list to the host in response to a first command received from the host, and set a performance level for at least one function from among the plurality of functions by adjusting internal resources of the storage device, in response to a second command received from the host.
