Features: This product only supports converting M.2 NGFFs SSDs drive with SATAs protocol to SATAs interfaces. to convert NVMe protocol M.2 SSDs to SFF-8643 interfaces, the motherboards needs to have SFF-8643 interfaces that supports PCIe protocol in order to use it. SATAs protocol M.2 SSDs supports 2242, 2260, and 2280 specifications. NVMe protocol M.2 SSDs supports 2230 2242 2260 2280 specifications. Be sure to confirm that your machine SFF-8643 interfaces and that it supports PCIe or NVMe. SFF-8643 interfaces that only support scannot be used.
