This M2 SFF-8643 converter turns the connector for a M2 PCIe SSD into a 36-pin SFF-8643 connector. This allows connecting the high performance 2.5" NVMe U.2 (SFF-8639) SSD to system via a SFF-8643 cable. It is a simple and economical solution for system that already has the M2 PCIe SSD sockets on board or on one of Addonics M2 PCIe SSD adapter.
