GLOTRENDS PU21 Dual U.2 to PCIe X8 4.0 Adapter, Support 2 x U.2 SSD, Without PCIe Splitter Function (PCIe Bifurcation Motherboard is Required)

By installing 2 x U.2 SSDs on this PCIe 4.0 X8 adapter, your computer will be able to access 2 x U.2 SSDs at the same time
Support Soft RAID in Intel/AMD platform, not support Mac Pro 5.1 (Note: To set up Intel's RAID-on-CPU (VROC), you need to purchase your license)
Set the PCIe Bifurcation mode of the corresponding PCIe slot in the BIOS, support X4X4X4X4 or X4X4X8 or Hyper M.2 X16 mode (Note: Can not support X8X4X4 mode)
Because this adapter does not support PCIe Bifurcation, it requires a motherboard that supports PCIe Bifurcation.
To reach PCIe 4.0 X4 (64Gbps) full speed, the CPU and motherboard PCIe slot and PCIe M.2 SSD should all be PCIe 4.0 features (Note: PCIe 4.0 is not supported on Intel CPUs below 11th generation)
Support OS Booting: Reinstall the OS, and set up BIOS/UEFI boot from this U.2 SSD
Plug-and-play in Windows 11/10/8/Linux/Mac OS (Note: Not support Windows 7). The new U.2 SSD needs to be initialized and formatted before it can be recognized by the computer host.
