SAS and SATA

SAS or serial-attached SCSI is the current connectivity to replace the previous generation parallel-attached SCSI (PAS) devices. Ultra320 was the highest level of parallel SCSI available, but SAS has since replaced it as the highest-performing SCSI technology.

SATA is a similar technology from the aspect of connection options. HBAs can be created using a single connector to connect both SAS and SATA devices.

Major SAS/SATA adapter manufacturers are Promise Technologies, Adaptec, HP, QLogic, Areca, LSI and ATTO Technology.
