Serial Advanced Technology Attachment (known as “ATA”), or S-ATA, is a computer bus technology that was designed for the transfer of information/data to and from a computer hard disk drive. Serial ATA is the successor to Integrated Drive Electronics (IDE), sometimes also called Parallel ATA (or P-ATA). One of the advantages of Serial ATA is its simplicity – one cable consisting of a minimum of four wires, allowing for connection in a point-to-point configuration between components/devices. Serial ATA transfer rates typically start at 150 Mega Bits per second (MBps), and can go as high as 600 MBps. Another advantage of Serial ATA cables is the thinner outline of the cable, allowing for efficient airflow within a computer or system enclosure, as well as allowing for smaller chassis design configurations. Power cables that are used for Serial ATA applications utilize a 15-pin wafer connector to deliver 3.3, 5, or 12 volts to ATA devices.
