A disk interface card includes a disk interface, a cache memory, a bus interface and a microprocessor. The disk interface card is electrically connected to a host disk interface of a host through a cable. The disk interface card can be cooperated with a conventional disk array card, which is able to connect with several hard drives, so as to form an external hard drive array. The external hard drive array can be connected to the host through the cable. The disk interface card passively uses the cache memory to store an access command from the host, and waits for the disk array card to come to read out the access command therefrom.
