In this paper, the enhanced ATA(AT Attachment Interface with Extension) interface that combines the price of ATA and intelligent operation of SCSI(Small Computer System Interface) is realized both performance and structure of general interface used to connect peripheral devices that are used in PC(Personal Computer). SCSI bus is for peripheral devices that have intelligent operation. It is excellent bus that has well-arranged command system and stable hardware structure. But is aspect of price this peripheral device has the difficulty in purchase because there is price difference more than two times compared with ATA peripheral device. Whereas, although ATA peripheral device had low performance in the early period, after the improvement its speed has almost etched to SCSI and its price is also excellent. In this paper, the enhanced interface structure to fulfill price and performance was suggested and materialized as the hardware using such two advantages.
