?Note?Do not Support Hardware Raid, only support the formation of soft raid in Win10 , or you may build raid via Third-party Software, and the 4 SSDs should be same model. The motherboard need support "PCIEX16 Bifurcation",otherwise, only one M.2 SSD can be recognized. ?Compatibility?Compatible with M.2 PCI-e NVMe SSDs: 80x22mm, 60x22mm and 42x22mm, 30x22mm.(Do not support any M.2 (SATA-Based B+M Key) SSD); Motherboard: X299, X399 and Most Servers supporting PCIe x16 Bifurcation. ?Fan & LED indicator?The unique fan design on our Quad NVMe PCIe Adapter ensures efficient heat dissipation, preventing your SSDs from overheating and ensuring optimal performance. A single LED indicator will display the working status of each SSD. ?Hardware requirement?The PCI-e 4.0/3.0 x16 Slot on Mobo is required to support PCIe x16 Bifurcation itself and could be set as"PCI-e x4x4x4x4" in BIOS. All of the SSDs are M.2 (M Key) NVMe SSD. Besides, the CPU has enough channels supported. ?Quad NVMe PCIe Adapter?This adapter allows you to add 4x NVMe SSDs simultaneously via PCI-e 4.0/3.0 x16 slot on the MOBO which is required to support PCIe x16 Bifurcation. Full-speed transmission up to 4x 32Gbps.
