An external storage, which can exchange data with a data transmission line of a data processing system, comprising:

• a management unit connected to the data transmission line;
• a buffer connected to the management unit for buffering data;
• and
• storage areas connected to the buffer for storing data;
• wherein said management unit comprises:
• a start-up module for receiving an instruction, said instruction corresponding to an operation and comprising keyword information and information on at least one storage area corresponding to the operation;
• a scan module for reading the data information of the at least one storage area to the buffer, each of the at least one storage area being smaller in capacity than the buffer;
• and
• a search module for searching the data information in the buffer for the data information matching the keyword information.
