M.2 M-key to quad SAS adapter

This 50 cm cable converts a single M.2 M-key SFF-8643 contact into four SAS SFF-8482 ports, letting server builders attach multiple SAS drives or backplanes to an NVME slot. It targets administrators who need dense storage expansion without adding a dedicated HBA card. The male-to-male Mini SAS wiring carries the high-speed lanes directly from the M.2 interface.

Plug-and-play with mechanical care

Installation is a simple plug-and-play process that requires no extra drivers or software, saving time for IT staff during upgrades. The main risk is physical: the M.2 M-key connector must be fully seated in the motherboard or riser, and the four SFF-8482 plugs need firm engagement to avoid intermittent links. Cable routing should avoid sharp bends that could stress the 18 cm tail near the M.2 end.

Lane and protocol boundaries

The SFF-8643 side exposes the lanes available from the host M.2 slot, so total throughput cannot exceed what that single NVME link provides. Each SFF-8482 port operates at SAS signalling rates, but the aggregate bandwidth is shared across all four ports. The cable does not add controller logic; it only breaks out the existing electrical connections, so the host must support bifurcation or port multiplication for all drives to be visible.

Questions about this item

How can I confirm the M.2 Mkey SFF-8643 to 4-port SAS SFF-8482 cable is working after installation?

The system should detect each attached NVME drive in BIOS or the OS disk utility without errors, and data transfers should run at expected SAS speeds.

What comes in the box and what must I source separately?

The package contains the 50 cm conversion cable with an M.2 Mkey SFF-8643 connector on one end and four SAS SFF-8482 ports on the other; you must provide the NVME drives, SAS backplane or controller, and any mounting hardware.

Which cable length should I choose for my server chassis?

The cable is 50 cm long; select this length when the M.2 slot and the four SAS SFF-8482 ports are within half a metre of each other.
