Quad M. 2 NVMe to PCIe 3.0
X8 Adapter: By installing 4 M. 2 NVMe SSDs (Support 22110/2280/2260/2242/2230 M. 2 NVMe SSD) on this PCIe 3.0 X8 adapter, your computer will be able to access 4 x M. 2 NVMe SSDs at the same time (Note: Not support M. 2 SATA SSD). ASM2824 Chip Built-in
PCIe Bifurcation: It can work with all kinds of motherboards (Note: The PCIe slot must be allocated with PCIe X8 lane bandwidth).
Upstream Bandwidth: 4 x M. 2 NVMe SSDs sharing PCIE 3.0 X8 bandwidth (64Gbits/s = 8GB/s max), it means 4 x M. 2 NVMe SSDs cannot opearte at full speed at the same time.
Hardware Platform: 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).
Support OS Booting: Reinstall the OS, and set up BIOS/UEFI boot from this M.
2 NVMe SSD (Note: Some motherboards are too old to support OS booting. In this case, M. 2 NVMe SSDs can be used as storage disks).
