A storage device may set a plurality of super memory blocks each including one or more of the plurality of memory blocks, each including one or more of the plurality of memory units. The storage device may migrate data stored in the first super memory block to a second super memory block among the super memory blocks when a first super memory block among the plurality of super memory blocks satisfies a first condition, and may increase a priority of a target memory unit when the target memory unit among the memory units included in the first super memory block satisfies a second condition.

The present technology relates to an electronic device. According to the present technology, a memory controller may include a garbage collection controller and a sustain detector. The garbage collection controller may generate garbage collection information including valid page count values of victim memory blocks on which garbage collection is to be performed among a plurality of memory blocks included in a memory device. The sustain detector in communication with the garbage collection controller may generate sustain information indicating whether random write performance for the memory device is in a sustain state in which a random write performance value related to a capability of the random write performance is greater than or equal to a threshold value based on the garbage collection information.
