1)Connectors: 1 x slimline SFF-8654 female and 1 x SFF-8639 U.2/U.3 female and 1 x SATA power.
2)The card transmits PCI Express 4.0/5.0 signals using the NVMe protocol.Data transfer rate up to 64Gbps, Supports NVM Express (NVMe) 1.2.
3)The speed and other properties is not changed,only form conversion interface.Transparent to the operating system and does not require any software drivers.
4)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.
5)This convertor expands the SFF-8639 U.2/U.3 by one SFF-8654 slimline interface. It can be connected e.g. one SSD by using an optional cable.
