The SAS (Serial Attached SCSI) interface is a type of interface used to connect storage devices, such as hard drives and solid state drives, to a computer or server. It uses a point-to-point topology, where each device has its own dedicated connection to the host, rather than sharing a common bus like with SATA. This allows for greater scalability and performance.

SAS was developed as a successor to the parallel SCSI (Small Computer System Interface) standard and is designed to handle high-speed data transfer rates and large storage capacity.
