8-Drive NVMe SSD to PCIe 4.0 X 16 Adapter Card with Active Cooling (88048 8-Drive NVMe Expansion Card, Plain) Visit the oaknode Store (Plain)

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.
