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.

When it is determined that a first super memory block among a plurality of super memory blocks satisfies an exchange condition, the storage device may exchange a first memory unit in the first super memory block with a second memory unit included in a second super memory block among the plurality of super memory blocks. In this case, the first memory unit is a bad memory unit and the second memory unit is a normal memory unit.
