M.2 to U.2 Adapter for Enterprise Storage

This adapter links an M.2 M-Key NVMe SSD to a U.2 SFF-8639 drive using SFF-8643 connectors, supplying power through SATA 15-pin and 7-pin left-angle cables. It targets system integrators building high-speed storage arrays in servers or data-centre racks. The 50 cm length suits typical chassis routing without excess slack.

Sustained Workload Reliability

Advanced EMI shielding and precision wiring maintain signal integrity at 32 Gbps during continuous database replication or virtualization tasks. Secure locking connectors resist vibration-induced disconnects in densely populated drive bays. The construction is rated for long-term operation in RAID and cloud-storage workloads where thermal cycling and constant I/O are standard.

PCIe and SAS Interface Limits

The cable complies with PCIe 3.0/4.0 and SAS 3.0 electrical specifications, capping throughput at 32 Gbps regardless of drive capability. It cannot exceed the lane count or protocol version defined by those standards. Builders needing higher bandwidth or different connector pinouts must select a different interconnect solution.

Questions about this item

How much power does the 50 cm adapter draw when running an NVMe SSD all day?

The adapter itself is passive and draws no measurable power; only the connected NVMe SSD and U.2 drive consume power during continuous operation.

Which connectors must my motherboard and power supply already provide for this adapter to work?

You need an M.2 M-Key slot, a U.2 SFF-8639 port, a SATA 15-pin power connector and a SATA 7-pin data connector.

Will the SFF-8643 to SFF-8639 link work with a PCIe 3.0 motherboard and an older U.2 drive?

Yes, the cable is compliant with PCIe 3.0 and SAS 3.0, so it will operate at the speed supported by the older hardware.
