  • 12 Gbps bandwidth capability for NVMe performance
  • Driver-free operation with latest operating systems
  • Enables server NVMe performance on client platform

M.2 to U.2 Adapter Cable

This cable converts an M.2 M-key NVMe SSD connection to an SFF-8643 Mini-SAS HD interface. It enables a 2.5" U.2 SSD to connect via an M.2 slot using the included SFF-8643 cable. The adapter supports a bandwidth capability of 12 Gbps for high-speed data transfer. It brings server-grade NVMe performance to a client platform without requiring additional drivers.

Compatibility Check

Verify that the host system provides an M.2 M-key slot wired for NVMe signalling. Ensure the 2.5" U.2 drive uses the SFF-8639 connector standard for proper mating. Confirm the operating system supports NVMe devices natively for driverless operation. The cable carries PCIe lanes directly so the platform must route them from the M.2 slot.

Build Integration

The adapter occupies an M.2 slot and routes signals to a standard SFF-8643 Mini-SAS HD port for the U.2 drive. It frees up 2.5" drive bays by allowing U.2 SSDs to be mounted elsewhere in the chassis. No external power adapter is included so the drive must receive power from the system backplane or a separate source. The 12 Gbps link maintains full NVMe throughput for demanding workloads.

Questions about this item

What connectors are included and do I need a separate cable?

The adapter has an M.2 M-Key slot on one side and an SFF-8643 Mini-SAS HD port on the other; an SFF-8643 to SFF-8639 cable is already included so no extra cable is required.

How do I choose between the listed connector types for my drive?

Use the M.2 M-Key side for an M.2 NVMe SSD and the SFF-8639 end for a 2.5" U.2 drive; the cable bridges those two interfaces directly.

What does the 12 Gbps bandwidth mean for my SSD speed?

The link supports up to 12 Gbps per lane, allowing a U.2 NVMe SSD to run at near-server performance when connected through the M.2 slot.
