QM2-4P-384 Quad M.2 2280 PCIe NVMe SSD Expansion Card - 4 Port PCI Express Adapter for High Speed Storage - Perfect for Gaming PCs, Workstations & Data Servers

I like this card, but I think I would need to use a faster than 10Gbd NIC to get full speed from it. I have not yet tested it in my PC, but I wish I would have experimented with it there before installing it in my NAS. Then I would have a better sense of what it is capable of. I am getting about 1000 GB per second read and 1200 GB/sec write speeds with 4 high speed SSDs installed.
