An memory device (HDD) storage system (10) has at least one storing location (16) in which an memory device (18) is received while the memory device is not supplied with an electric power, at least one docking location (22) where the memory device is supplied with the electric power so that data can be stored in the memory device and retrieved from the memory device, and a transport device (30) for transporting the memory device between the shelf (16) and the docking location (22). Alternatively, a switching controller (110) connects a system controller (26) and also a power source (118) to an immovably secured memory device (18).
