Description: Dual NVME , PCI-E X16 split card. PCI-E X16 motherboard slots are supported. Pci-e3.0 and PCI-e4.0 standard mission speeds are supported. Four X4 full-channel full-speed NVME SSD and M.2 PCI-E interface devices are supported. high-power DC chip is adopted to the stable operation of SSD and M.2 PCI-E equipment. Adopt high-end PCB circuit board, gold plating process, with good conductivity, strong wear resistance, oxidation resistance and high fire protection level. Thickened gold finger, PCI-E X16 interface, thick gold sinking process, better contact and more stable mission speed. The working state is known at any time. It is always on when the plug-in tray is powered on, and flashes when reading and writing. E-sports comes standard, abandoning SATA3 hard disk of old motherboard, upgrading M.2 hard disk interface, speeding up the startup speed, and making cool. Reject the software crash, further improve the hard disk performance, meet the needs of design/video and other fields, and give full play to the computer performance.
