• 8-slot M.2 NVMe to PCIe 4.0 x16 Adapter (OS boot not supported) - Expands 8 M.2 NVMe Key M ports via PCIe 4.0 x16 interface to provide up to 256Gb/s bandwidth. Supports M.2 NVMe SSDs in 2230/2260/2280/22110 sizes.
• Powered by the PEX88048 controller with PCIe switching technology – works with all motherboards, including Mac Pro, no need for motherboard/CPU PCIe bifurcation support.
• The CW-PCIE-8M2 Expansion Card provides high-capacity SSD storage and a high-performance switching engine with eight independent M.2 slots and Broadcom's 4th generation switching chip providing PCle4.0x4 signaling on each M.2 port while supporting up to 64TB of storage.
• The use of expansion cards for the PCI-Ex16 slot interface on the motherboard enables each M.2VNMe SSD to interface directly with the CPU without the need for BIOS splitting of signals, ensuring maximum transfer performance and near-instant response times.
• Two SFF-8654 (8i) port inputs, each port supports PCIE4.0X8 signal input, two ports with a total of 16 signals, providing two kinds of signal access, SFF-8654 port signals and CoLay signals with PCI-E x16 gold finger, the OPCI-E gold finger using the gold transition process, in line with the PCIExpress4.0 specification and SFF-8654 port CoLay signals, two kinds of access, one or the other. 8654 port CoLay signal, two kinds of access methods, choose one.
