Vszerda U.2 SFF-8639 to M.2 SFF-8643 Cable

This 50 cm internal cable connects a U.2 NVME SSD using an SFF-8639 interface to a mainboard or controller equipped with an M.2 SFF-8643 Mini SAS HD port. It supports PCIe 3.0 x4 signalling for 4 GBps throughput. The cable is sold alone without any adapter or add-in card included.

Builders linking U.2 drives to SFF-8643 ports

Suits system integrators adding enterprise U.2 storage to a workstation or server board that exposes an SFF-8643 connector. Not for users who need a complete kit with a mounting bracket or PCIe adapter card, nor for connections that require a different port type or longer reach than 50 cm.

PCIe 3.0 x4 at 4 GBps over SFF-8639 to SFF-8643

The link width and protocol determine whether the SSD can run at its rated speed; this cable carries four PCIe 3.0 lanes end-to-end. Verify that the host port is wired for PCIe and not solely for SAS, and confirm the 50 cm length fits your chassis routing before purchase.
