Dual NVME, PCI-E X8 split card. PCI-E X8 and X16 motherboard slots are supported. PCI-e3.0 and PCI-e4.0 standard transmission speeds are supported. Two full-speed NVME X4 SSDs and M.2 PCI-E interface devices are supported. Imported high-power DC chip is adopted to ensure the stable operation of SSD and M.2 PCI-E devices. Adopt high-end PCB board, plating process, with good conductivity, strong wear resistance, oxidation resistance and high fire protection level. Thickened gold finger, PCI-E X8 interface, thick gold sinking process, better contact and more stable transmission speed. The working status 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 the SATA3 hard drive of the old motherboard, upgrading the M.2 hard drive interface, accelerating the boot speed and making it cool. Reject software crashes, further improve hard drive performance, meet the needs of /video and other fields,
