High‑Speed Transmission with Compact, Modern Design

SFF‑8087 (Mini SAS 4i) – Internal SAS 2.0 Interface

The SFF‑8087 connector is a 36‑pin Mini SAS interface featuring a plastic latch mechanism commonly used on Mini SAS 4i RAID cards. It is designed for internal SAS interconnects, typically linking SAS HBAs to internal drive subsystems. Fully compliant with SAS 2.0, the SFF‑8087 supports 6Gbps data transfer rates and up to four SAS lanes, making it suitable for bandwidth‑intensive workloads inside servers and storage racks.

SFF‑8643 (HD Mini SAS) – Internal SAS 3.0 Interface

The SFF‑8643 connector is a 36‑pin HD Mini SAS interface engineered for next‑generation internal SAS connections. Built with a compact plastic housing, it supports SAS 3.0 and delivers data transfer rates of up to 12Gbps, doubling the performance of SAS 2.0. It is widely used in modern RAID controllers, backplanes, and high‑density storage systems.

Together, SFF‑8087 and SFF‑8643 support up to four SAS ports (four channels), enabling seamless connectivity between older SAS infrastructures and newer SAS 3.0 devices.
