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) | OS compatibility: Plug-and-play in Windows 11/10/8/Linux/Mac OS (Note: Not support Windows 7). The new M.2 NVMe SSD needs to be initialized and formatted before it can be recognized by the computer host. | Silent Heatsink Fan ensures this adapter runs for a long time without losing performance.
