1. The PCIe X4 M.2 M KEY NVMe SSD adapter is a multifunctional NVMe conversion card that can support the PCIe protocol NVMe SSD to connect directly to the motherboard, or support the SATA protocol NVMe SSD to connect to the motherboard SATA port through a SATA cable. 2. It supports ultra-fast PCI Express V3.0 X4 channel transmission bandwidth up to 32GT/S, and supports serial ATA v3.0 transmission to 6Gbps. 3. Through the adapter, the system operation speed can be increased, and the efficiency of office and entertainment can be improved. 4. Application installation: The M-Key interface can be inserted into the M.2 NVMe SATA protocol SSD, and then the SATA cable is inserted to connect to the motherboard, using PCI-E power supply, no external power supply is required. 5. : 10, 8, 8.1, Server 2012 R2, Linux, Fedora, SUSE, , native drivers all support PCIe NVMe. No driver is needed, because the driver is for the operation. The system is transparent and needs to support the NVMe protocol Product Name: PCI-E X4 M.2 Key M NVMe SSD Adapter Card Applicable type: M.2 NVMe SSD conversion Bus slot: PCIe X4 rev3.0 Media interface: 1 x M.2 Key M NVMe SSD connector SSD type: M.2 Key M SSD size: 2230, 2242, 2260 and 2280, 22110 drives Compliant with PCI Express specification revision 3.0, backward compatible with PCIE V2.0 and V1.0 motherboards Compliant with Serial ATA specification revision 3.0 Support M.2 Key M NVMe SSD, including 2230, 2242, 2260 and 2280, 22110 drives Support any "M" key M.2 SSD Drive sizes are 80, 60, 42 and 30mm colour:Black Material:PCB+metal Package Contents: 1 x PCI-E X4 M.2 Key M NVMe SSD adapter card 1 x screw with screwdriver Only the above package content, other products are not included.
