A management apparatus for multi-storage mediums, comprising:

• a memory;
• a processor;
• and
• one or more computer programs stored in the memory and executable on the processor, wherein the one or more computer programs comprise:
• instructions for scanning a plurality of storage mediums to identify the storage medium operating in an online mode;
• instructions for configuring the storage medium operating in the online mode as a first storage medium;
• instructions for establishing a doubly linked list by a controller, wherein the doubly linked list records storage mediums operating in the online mode;
• instructions for determining whether the first storage medium is in a register table;
• instructions for turning on a switching mode of the first storage medium upon determining the first storage medium is in the register table;
• and
• instructions for retrieving a switching command via a storage layer, wherein the switching command is generated by the controller in response to user request inputted from an input device, and the switching command is configured to associate one of the storage medium with a current operation pointer.
