Serial Attached SCSI (SAS) is a high-speed data storage interface designed for high-throughput and fast data access. Intended primarily for data storage centers, the SAS interface is backwards compatible with SATA. 

This allows the user to mix more expensive, lower-capacity SAS drives for applications that require faster data access and higher reliability, with lower-cost, higher-capacity SATA drives for applications with lower access speed requirements. 

Positive and passive latching ensures that the plug remains mated to receptacle

All internal mini SAS assemblies are capable of supporting SAS/SATA generation I and II bandwidths
