A7. SAS is used in the same environments in which SCSI and Fibre Channel play. SAS is designed to be used in high availability, enterprise environments where maximum random performance is required. SATA on the other hand is optimized for sequential I/O operations where the requirement is to transfer large sequential blocks of data to and from a drive. Installations currently using SATA will probably not want to migrate to SAS until comparable cost/performance levels can be reached with SAS.
