xiwai NGFF 4X NVME M-Key M.2 SSD to PCIE Express 5.0 Gen5 Gen4 X16 Raid Card Detachable Bifurcation VROC Raid0 Hyper Adapter

NVMe PCIe add-in cards can use up to 16 lanes in an x16 slot, thus having up to 64 GB/s of bandwidth available to them with PCIe 5.0; having up to 32GB/s of bandwidth available to them with PCIe 4.0 ^^ The bandwidth for each PCIe 5.0 lane is 4 GB/s. 4 GB/s per lane means that if you use a PCI-Express 5.0 x16 device, it would have up to 64 GB/s of bandwidth available to it. The card does not support actual hardware raid, the product only supports the formation of Virtual raid under win10/win10 system, or the use of other third-party software to build raid.

^^ VROC is an enterprise RAID solution that unleashes the performance of NVMe SSDs, enabled by a feature in Scalable processors called Volume Management Device (VMD), an integrated controller inside the CPU PCIe root complex. VROC enables these benefits without the complexity, cost, and power consumption of traditional hardware RAID host bus adapter (HBA) cards placed between the drives and the CPU ^^ Built-in multiple sets of high-power DC modules for sustainable and stable work; The innovative design can accommodate four NVMEs of the chassis, and can support simultaneous operation ^^ Only supports motherboards with bifurcation detachable PCI-E channels; Control the operation of four disks based on the motherboard PCIE channel, The motherboard without PCIE signal split can only recognize one disk; NVME four-disks design, Stable installation, Can run four NVME disks at full speed at the same time
