Table 2. Sff8087 Internal Connector With One Sgpio Connector Pin-Out - Intel RS2SG244 User Manual

SAS/SATA Connector Pin-out
Signal names are with respect to the host; the device connected to the host reverses the
signal names. Transmit pins connect to receive pins on the other device. The SAS/SATA
connector is keyed at pin 1. These pin-outs for the serial ATA connector are not
compatible with the legacy PATA connector.
