Description: Dual NVME RAID, PCI-E X16 split card. PCI-E X16 motherboard slots are supported. Pci-e3.0 and PCI-e4.0 standard transmission 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, surface 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 transmission 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 of motherboard, upgrading M.2 interface, speeding up the startup speed, and making cool.Reject the software crash, further the performance, meet the needs of design/video and other fields, and give full play to the computer performance.Specifications:Name: Dual NVME RAID PCI-E X16 split cardType: PH44PRO support: M KEY Transmission speed: 4*32GbpsNotes:Instructions for use:1. the motherboard must supportThe main board supports PCI-E split function and can set PCI-E X4X4X4X4 or mode;The main board supports PCI-E RAID function; motherboard supports the function of HyperM.2X16 expansion card;Different motherboards have different PCI-E split channels, and some motherboards have a PCI-E RAID of X8 X4 X4.
