The SFF-8482 is a connector design for interfacing a connection for SAS drives, both SAS Hard drives and SAS SSD drives.
The SFF-8482 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-8482 can be incorporated onto a pcb ‘”docking” backplane for multiple drives, onto a single-drive “T-Card” adapters such as CS Electronics’ ADP-4200 and ADP-4000, or even used as a cable interface to plug directly onto a drive.
The SFF-8482 is compliant with the SAS 2.0 spec, and supports 6Gb/s data transfer protocol
The newer version of the SFF-8482 drive interface connector interface is the SFF-8680, which visually is very similar, except that the SFF-8680 was design for the faster SAS 3.0 12Gb/s speeds.
