During operation, the FPGA unit 141 detects the attributes of a SAS or SATA signal through each hard disk signal interface 145 to adopt a corresponding signal version processing module to electrically couple a SAS or SATA signal to each hard disk port 130. SATA hard disk for processing. As this authoring system integrates the processing modules of SAS version and various SATA versions in the FPGA unit 141 by means of firmware, it can not only automatically determine which type of SAS hard disk the inserted hard disk is. The version of the SATA hard disk is convenient for the operator, and it can also eliminate the I/O control circuit required by the general copy device and the dependence on the general operating system.
