Abstract: A storage device is provided. The storage device includes a memory device including a memory cell array configured to store metadata and main data and a storage controller configured to access the memory device and control the memory device, wherein the storage controller is configured to read data from the memory device at a speed adaptively varying to a first read speed or a second read speed according to a state of the memory device, the second read speed being faster than the first read speed.
