I have an Asrock MB with N100 CPU, which only has PCIe3 x2 (with two lanes). However I want to run 4 SSDs on it.
I've found an adapter board for two SSDs that connects to a PCIe3x1:

Given your knowledge, is there an easy way to run two of these boards on a single PCIe 3.0 x2 port? Maybe even with some bodge wires? Sadly I can't find a single board that would hold 4 SSDs.

Hi So your design is very very great and quite usefull to understand the bifurcation and the trace design. Thanks for that. Also, i did see that you may have done a slim adapter for network card, using oculink connector. I try to figure out how to properly power the card and around a 8643 connector.. Do you think you can also share your schematic for that small one ?

Thanks in advance, very appreciated.
