technology. The SAS protocols and SATA protocols use a thin, 7-wire
connector instead of the 68-wire SCSI cable or 26-wire ATA cable. The
SAS/SATA connector and cable are easier to manipulate, allow
connections to smaller devices, and do not inhibit airflow. The point-to-
point SATA architecture eliminates inherent difficulties created by the
legacy ATA master-slave architecture, while maintaining compatibility
with existing ATA firmware.
PCI Express is a local bus system designed to increase data transfers
