A SATA connection is a serial connection, and the data connector has four lines: two for the signal (one each way), and two for power (hot and neutral). SATA cables have smaller connectors, and the wires are housed in a protective sheath that's about 1/6 (rough guess) of the width of an ATA ribbon cable. In addition, SATA technology allows for much faster speeds than ATA was going to be able to allow.
