Vszerda SF-094 SFF-8643 to NGFF hard drive adapter

Vszerda SF-094 U.2 to M.2 Adapter

The Vszerda SF-094 is a printed-circuit adapter that converts a U.2 (SFF-8639) backplane or cable connection to an M-key M.2 slot. It carries a PCIe 3.0 x4 electrical link rated at 4 GBps, allowing an NVME SSD to connect directly to a server or workstation mainboard that provides an SFF-8643 Mini SAS HD port.

Suits NVME drives on U.2 infrastructure

This adapter suits builders installing an M-key NVME SSD into a system wired for U.2 drive bays or SFF-8643 host connectors. It is not for drives that lack an M-key edge connector, nor for platforms that cannot supply a PCIe 3.0 x4 link to the U.2 port. Legacy operating systems such as Windows 7 require a separate NVME driver update before the drive will be recognised.

PCIe 3.0 x4 lane width decides compatibility

The single specification that determines whether this part works is the host providing a true PCIe 3.0 x4 connection to the SFF-8643 connector. If the mainboard or backplane routes fewer lanes or an older PCIe generation, the SSD will not reach the stated 4 GBps throughput or may fail to enumerate.
