Vszerda M.2 M-Key to SFF-8643 Adapter

This adapter converts an M.2 M-Key NVMe SSD connection to an SFF-8643 Mini SAS interface. A 3.3FT SFF-8643 to SFF-8639 cable is included to link 2.5" U.2 SSDs. The card supports M.2 2260 and 2280 form factors and works with Intel 750 Series U.2 SSDs. No drivers are required on current operating systems.

Compatibility check before ordering

Verify that your motherboard has an available M.2 M-Key slot compatible with PCIe 4.0 or 3.0 signalling. Confirm the target U.2 drive uses an SFF-8639 connector and fits the 2.5" form factor. Ensure the 3.3FT cable length suits your internal routing. The adapter operates up to 64GT/s within the PCIe 4.0 specification.

Suits builders adding U.2 storage via M.2

Ideal for integrators connecting enterprise U.2 drives such as Intel p3600 or p3700 models to consumer or workstation boards. Not for users needing SATA protocol support, external enclosures, or adapters for M.2 SATA drives. Buyers requiring longer cables or different connector orientations should look elsewhere.

Questions about this item

What connectors and cable come with the Vszerda M.2 to SFF-8643 adapter?

The package includes an M.2 M-Key to SFF-8643 expansion card and a 3.3-foot SFF-8643 to SFF-8639 cable for connecting a 2.5-inch U.2 SSD to an M.2 slot.

Which M.2 drive lengths does the adapter support?

The adapter fits M.2 2260 and 2280 drives, covering the two most common NVMe stick lengths.

What does the 64 GT/s transfer rate mean for real-world SSD performance?

64 GT/s is the PCIe 4.0 signalling ceiling; actual throughput depends on the SSD and host controller, but the link will not bottleneck current U.2 or M.2 NVMe drives.
