An air conditioner includes an outdoor unit including a compressor, first and second indoor heat exchangers to receive a refrigerant from the outdoor unit, the second indoor heat exchanger receiving the refrigerant independently of the first indoor heat exchanger, and a fan disposed between the first and second indoor heat exchangers. First and second refrigerant pipes form flow paths between the outdoor unit and the first and second indoor heat exchangers. First and second expansion valves are disposed on the first and second refrigerant pipes. Third and fourth refrigerant pipes form flow paths between the compressor and the first and second indoor heat exchangers. A first opening and closing valve selectively opens and closes a fifth refrigerant pipe to selectively allow refrigerant to flow between the second and third refrigerant pipes. Second and third opening and closing valves selectively open and close the second and third refrigerant pipes.

A storage device includes a nonvolatile memory device that includes a first storage area and a second storage area. A controller of the storage device controls the nonvolatile memory device and performs a read reclaim operation of reading data stored in the first storage area of the nonvolatile memory device and writing the read data in the second storage area. In the read reclaim operation, the controller is further configured to allow the nonvolatile memory device to perform sample read operations on the first storage area and to determine locations of the second storage area, at which the data are to be written, based on results of the sample read operations.
