When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of

Drive Interface Connectors

Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one
connector matches a tab or a filled-in hole on the other connector. Keyed connectors ensure that the
pin-1 wire in the cable goes to the pin-1 end of the connector. The pin-1 end of a connector on a board
or a card is usually indicated by a silk-screened "1"printed directly on the board or card.
