    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)

    (2) Write a Review
    • 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.

    PCIe Adapter: add 2 x U. 2 SSD onto a single PCIe X8 host adapter, so you can access 2 x U. 2 SSD individually, or set up soft RAID in Windows/Linux/3rd party software.
    U. 2 RAID for
    Intel/AMD Platform: Support U. 2 SSD RAID-on-CPU (VROC) in the Intel Platform, but you need to purchase an Intel VROC license by yourself. Support U. 2 RAID in AMD Platform. Not compatible with Mac Pro 5.1
    Note: Without the PCIe splitter function in this host adapter, so motherboard must support PCIe Bifurcation. Otherwise, only one U. 2 SSD will be recognized. If you are not sure PCIe Bifurcation of your motherboard, please consult the motherboard manufacturer or contact us via an Amazon message
    Please set the PCIe splitter in BIOS/UEFI into X4X4X4X4 or X4X4X8 or Hyper M. 2 X16 mode.
    Note: X8X4X4 mode will not work.
    Please make sure BIOS/UEFI supports native NVMe and OS boot from the PCIe lane, then this PU21 supports OS boot from U. 2 SSD or U. 2 RAID.
    Compatible with PCIe 4.0 / 3.0 / 2.0, and install into PCI-Express X8/X16 lane. To reach PCIe 4.0 speed, make sure your CPU and motherboard and U. 2 SSDs are all PCIe 4.0 enabled. To reach PCIe X8 full bandwidth, setup 2 x U. 2 SSD into RAID 0 mode.
