Dual M.2 PCIe SSD Host Adapter
  • Add 2 x M.2 PCIe (NVMe/AHCI) SSD (M-Key) onto a single PCIe X8 host adapter, so you can access 2 x M.2 NVMe SSD at the same time
  • Support soft RAID in Windows/Linux/3rd party software
  • Support M.2 NVMe SSD RAID-on-CPU (VROC) in the Intel Platform, but you need to purchase an Intel VROC license by yourself
  • Support M.2 NVMe RAID in AMD Platform
  • Not compatible with Mac Pro 5.1
  • The gap between the two NVMe slot is 3mm

PCIE Bifurcation Setup in BIOS/UEFI
  • Noted: This Dual M.2 PCIe SSD Host Adapter can not splitter PCIE X8 to PCIe X4X4, so your motherboard must support PCIE Bifurcation function. Otherwise, only one M.2 PCIe SSD will be recognized. If you are not sure PCIe Bifurcation of your motherboard, please provide the motherboard information, and we will reply within 24 hours.
  • Setup PCIE splitter in BIOS/UEFI into X4X4X4X4 or X4X4 (Compatible with Hyper M.2 X16 mode in ASUS).
  • Note: In mode X8X4X4, only one M.2 NVMe SSD will be recognized.

Soft RAID in Window 10
  • When you find 2 separate M.2 NVMe SSD in Disk Management of Windows 10
  • Right click the disk volume, which you want to setup soft RAID
  • A pop-up window appears, click the option (Spanned/Striped/Mirrored)
  • Noted: You can setup soft RAID in Linux/Mac/3rd party software also.
