The SFF-8680 is the latest connector design for interfacing a connection to a SAS drive – both SAS Hard drives and SAS SSD drives.
The SFF-8680 is a 29-pin connector with a plastic body, and configured with 15 pins that support the power requirements of the drive, and (2) groups of 7 pins that carry the SAS data signals.
The SFF-8680 supports 2 SAS ports (lanes) to/from the drive.
The SFF-8680 can be incorporated onto a pcb “docking backplane” for multiple drives, onto a single-drive “T-Card” adapters such as CS Electronics’ ADP-4480 and ADP-4380, or even used as a cable interface to plug directly onto a drive.
The SFF-8680 is compliant with the latest SAS 3.0 spec, and supports 12Gb/s data transfer protocol
This newer SFF-8680 drive interface connector interfaces has essentially replaced the older SFF-8482 drive interface connector
