SFF-8639（‘U.2′）
The SFF-8639 is the latest connector design for connecting MultiLink SAS drives or PCIe drives (including hard drives and SSD drives). It was recently renamed “U.2″ by the SSD Minitool group.
The SFF-8639 is a revised version of the SFF-8680, which is a 29-pin 2-channel SAS driver interface. The SFF-8639 U.2 is a 68-pin driver interface connector with higher signal quality and support for 12Gb/s SAS and Gen 3 x4 PCIe or PCI Express NVMe.
The SFF-8639 / U.2 connector can be integrated into the pcb “butt board” of multiple drives, or into a single drive “T-Card” adapter.
SFF-8680
The SFF-8680 is the latest connector design for connecting SAS drives – SAS hard drives and SAS SSD drives.
The SFF-8680 is a 29-pin connector with a plastic body configured with 15 pins to support the drive’s power requirements, and (2) 7 sets of pins for transmitting SAS data signals.
The SFF-8680 supports connections between two SAS ports (channels) and drives.
The SFF-8680 can be integrated into a pcb “butt board” for multiple drives, or into a single driver “T-Card” adapter.
The SFF-8680 complies with the latest SAS 3.0 specification and supports the 12Gb/s data transfer protocol.
This newer SFF-8680 driver interface connector interface essentially replaces the older SFF-8482 driver interface connector.
SFF-8482
The SFF-8482 is a connector design for connection of SAS drives, SAS hard drives, and SAS SSD drives.
The SFF-8482 is a 29-pin connector with a plastic body configured with 15 pins to support the power requirements of the drive; (2) 7 sets of pins for transmitting SAS data signals.
The SFF-8482 supports connections between two SAS ports (channels) and drives.
The SFF-8482 can be integrated into the pcb “docking” backplane of multiple drives, mounted on a single drive “T-Card” adapter.
The SFF-8484 interface is mainly used on SAS 4i array cards as an internal SAS connection cable. Supports 12Gbps bandwidth.
