Do PCIe bifurcation cards with 4 M.2 A+E slots exist? (lemmy.ml)

I have seen several cards that will do up to 4 NVMe from a single x16 slot (with MB and CPU that support bifurcation), but I have only found cards that are 1 PCIe slot to 1 M.2 A+E.

I think one way to do this would be to have a regular bifurcation x16 to 4 x4s and then use the 1x cards. But are there other options?

The reason I am asking is because I am procrastinating on other things I am supposed to be doing. I have no actual need for this and putting 4 wifi cards so close probably creates horrible interference anyway.

Asus sells these cards, but the motherboard needs to support 4 way bifurcation. Most only support two way. There’s definitely double nvme cards that have a wider compatibility

Yeah there's a bunch of them out there. I've had one running for a while now. Don't have the specific model but it's something like this: https://a.co/d/2v5M3U3
