Vszerda U.2 SFF-8639 to M.2 SFF-8643 NVME SAS Cable 50cm

U.2 SFF-8639 to M.2 SFF-8643 cable

This 50 cm internal cable connects a U.2 SFF-8639 NVME PCIe SSD to a mainboard M.2 SFF-8643 Mini SAS HD header. It supports PCIe 3.0 x4 signalling and carries a 4 GBps data rate. The cable is sold alone; no adapter or controller card is included.

Builder fitting a U.2 SSD to an Ultra M.2 card

The cable suits builders installing a U.2 NVME drive onto a mainboard with an SFF-8643 Mini SAS HD connector, such as those labelled Hyper Kit Storage controller or Ultra M.2 Card. It will not work for systems lacking an SFF-8643 header or for drives using a different interface.

PCIe 3.0 x4 at 4 GBps over 50 cm

The link runs at PCIe 3.0 x4 with a stated 4 GBps throughput across the 50 cm length. This bandwidth figure determines whether the cable meets the performance needs of the target SSD.
