Serial Attached SCSI SFF 8482 has the same form factor as Serial ATA with the addition of a "bump" to key it specifically for SAS. Also called SAS Backplane Connector. (Serial ATA drives can be plugged into SAS controllers, but SAS drives will not function with a Serial ATA controller; hence, the necessity for the key bump on the connector.)

The capabilities of Serial Attach SCSI have been developed to meet the evolving needs of high end server applications. These challenging needs include scalability, performance, reliability and manageability, while leveraging a common electrical and physical connection interface with Serial ATA. This compatibility provides users with unprecedented choices for server and sub-system deployment.

Serial Attach SCSI uses a point-to-point architecture which works in conjunction with PCI Express and other high-speed architectures on the market such as Serial ATA. Both Serial Attach SCSI and Serial ATA drives are compatible with Serial Attach SCSI Backplane receptacles. Molex offers a wide range of PCB attachment and size options for any application.


  • Point to Point Topology
    • Ensures maximum bandwidth by providing dedicated signal path for each device, eliminates daisy-chain slowdowns and addresses conflicts
  • Disk/Backplane Interoperatbility with Serial ATA
    • Gives flexibility to specify best drive for intended use: SAS for transactional/online performance and reliability, Serial ATA for near line and backup/restore storage
  • Hot Plug, Blind-mate connections
    • Add/remove drives without system shutdown, facilitates connection in cramped or inaccessible installations
  • 3.0 Gb/s transfer rate
    • Sets new standards for enterprise-class performance, second generation on track for 6.0Gb/s throughput
