How does Serial ATA work?
As with all computer technologies the need for speed has become paramount. The Serial ATA interface is no exception to this with speeds of up to 3Gbits/sec and greater being boasted. To achieve this increase in speed the interface has undergone a complete re-design and the once familiar 40 Way (80 wire) ribbon cable has completely disappeared. To overcome a number of problems, and to achieve this high transfer rate, the Serial ATA interface was defined. The new interface employs a high-speed differential pair signaling technique, the data being transmitted over two separate pairs, and a separate power connector (figure 5) supplies the power for the device.
