Feature: 1. Quad M.2 NVMe to PCIe 4.0 X16 Adapter: By installing 4 M.2 NVMe SSDs (supports 22110 2280 2260 2242 2230 M.2 NVMe SSDs) on this PCIe 4.0 X16 adapter, your computer will be able to access up to 4 M.2 NVMe SSDs simultaneously. 2. Hardware Platform: for Windows 8 10 system side has its own driver, for Windows 10 can realize soft RAID (other systems need to install the driver). Support for Intel, for AMD platform soft RAID, does not support for OS X Pro 5.1 (Note: To set up RAID on CPU for Intel (for VROC), you need to purchase a license) 3. Cautions: Since this adapter does not support for PCIe Bifurcation, it requires a motherboard that supports for PCIe Bifurcation. Otherwise, only the NVMe 1 port can recognize NVMe SSDs. Please check the PCIe Expansion Slot section of the motherboard manual on the motherboard manufacturer's website before purchasing. 4. High Speed Transfer Signal: 4Gx32Gbps full speed signal, solid PCIE X16 interface, support PCIE3.0 4.0 high speed transfer protocol, CPU and motherboard PCIe slots and PCIe M.2 SSDs should have PCIe 4.0 function. (Note: PCIe 4.0 is not supported on for Intel CPUs below 11th generation.) 5. OS Compatibility: Plug and play, suitable for Windows 11 10 8, for Linux, for OS X (Note: for Windows 7 is not supported). New M.2 NVMe SSDs need to be initialized and formatted to be recognized by the computer host. Set the PCIe Bifurcation mode of the corresponding PCIe slot in BIOS, support X4X4X4X4X4 or for Hyper M.2 X16 mode.
