xiwai Hard Disk Drive Converter SFF-8643 PCI-E 4.0 Female to SFF-8639 U.2 U.3 NVME PCIe PCI-Express SSD Adapter Card with SATA 5V+12V Power Cable for Mainboard

Connectors: 1 x SFF-8643 female and 1 x SFF-8639 U.2 U.3 female and 1 x SATA power. The vertical connector allowing you to connect it to a female port, even if space around the port is limited., Data transfer rate up to 64Gbps, Supports NVM Express (NVMe) 1.2. The card transmits PCI Express 4.0/5.0 signals using the NVMe protocol., This convertor expands the SFF-8639 U.2 U.3 by one SFF-8643 interface. It can be connected e.g. one SSD by using an optional cable., The speed and other properties is not changed,only form conversion interface.Transparent to the operating system and does not require any software drivers., U.3 drives are still backward compatible with U.2, though—the U.3 drives determine which host type it is inserted into (by using different combinations of HPT0 and HTP1 being open or ground), and configure the data lanes on power-up. U.3 drives can still act as dual-port NVMe drives in supporting systems.
