• Sas is a serial point to point enterprise level device interface that leverages the proven scsi protocol set sas is a convergence of the advantages of sata scsi and fibre channel and it is the future mainstay of the enterprise and high end workstation storage markets sas offers a higher bandwidth per pin than parallel scsi and it improves signal and data integrity p.8
• Sas controllers leverage a common electrical and physical connection interface that is compatible with serial ata technology the sas protocols and the sata iii protocols use a thin 7 wire connector instead of the 68 wire scsi cable or 26 wire ata cable the sas sata iii connector and cable are easier to manipulate allow connections to smaller devices and do not inhibit airflow the point to point sata iii architecture eliminates inherent difficulties created by the legacy ata master slave architecture while maintaining compatibility with existing ata firmware p.8
