A drive device capable of preventing a drop in the data transfer rate, even when write instructions from a host device are given with commands having a short write data length. If the write end address of one of a plurality of ATA commands issued by a host device 2 is consecutive with the write start address of the next ATA command, a command analysis unit 11 has data writing to an SD card 1 by the consecutive commands performed in a single process. As a result, overheads when writing data to SD cards are incurred only once, allowing the transfer rate to be improved.
