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.

Duress in American law. In jurisprudence, duress or coercion refers to a situation whereby a person performs an act as a result of violence, threat, or other pressure against the person.

Duress is pressure exerted upon a person to coerce that person to perform an act they ordinarily would not perform. The notion of duress must be distinguished both from undue influence in the civil law.
