4 disk M.2 NVMe SSD PCIe X16 Adapter PCI Express 4.0 X16 Switch to 4 Ports M.2 Adapter Card Supports RAID PCIe Bifurcation Description: 1.4-disk SSD array card, extended at the same time, 4*32Gbps full-speed signal, with cooling fan. 2.Adopt high-quality ball bearing ball fan, with long service life, high efficiency and silence. 3.Active cooling of NVME SSD by fan ensures stable operation of SSD, and the transmission speed of SSD will not decrease due to excessive temperature. 4.Support 4-disk soft RAID, and realize soft RAID under WIN10. 4-disk has good performance and RAID stability. 5.Give you a full-speed experience, and use imported high-power DC chips to ensure the stable operation of SSD and M.2 PCI-E devices. 6.Pci-e3.0 and PCI-e4.0 standard transmission speeds are supported. 7.It supports four X4 full-channel full-speed NVME SSD and M.2 PCI-E interface devices. 8.Adopt high-end PCB circuit board, surface gold plating process, with good conductivity, strong wear resistance, oxidation resistance and high fire protection level. Specifications: Name: 4 sets of NVME RAID PCI-E X16 split card Type: PH44F Hard disk support: SSD/M.2 PCI-E device of M. 2 NVME protocol Transmission speed: 4*32Gbps Packing: packed in neutral cowhide box Packing size: 19.5*13*3.2CM Product weight: product fan baffle 148.8G Package Included: 1*4 sets of NVME RAID PCI-E X16 split card Notes: This product can run 4 NVME at the same time, but the motherboard must support PCIE signal splitting. The motherboard must support: 1. The motherboard supports the PCI-E splitting function and can set the PCI-E X4X4X4 or 4X4 mode; many motherboards are a channel for sharing PCI-E to determine that the motherboard can support the PCI-E splitting function, but it cannot recognize so much. M.2 SSD or device, please remove or replace other PCI-E devices, such as graphics cards, extended cards, and board NVMe SSDs. 2. Need CPU support, you can refer to the forms in the qualification certificate. It is part of the main board and model supporting, as well as splitting methods.
