PCIe testing on the Raspberry Pi 5, and NAS project, part 8. The big one

This is a big one.
This is a PCIe x8 to 4(qty) m.2 PCIe add-on card, with the PLX PEX8724 PCIe 3.0 switch chipset
tl;dr it works on the pi5

Details:
"Plan A" is to have both a 10GbE NIC /and/ a SAS storage controller attached to the Pi. I have confirmed a working 10G NIC and SAS controller.
To get them both on the pi I need a PCIe switch, and for maximum performance, I want a gen3 switch specifically.

Of the few options for gen3 PCIe switches, the fastest (shipping) route would be one of the multi-m.2 cards on Amazon (not the bifurcation cards). They're meant for nvme SSDs, but technically they're just a PCIe switch on an add-on card, so other PCIe devices should work with adapters.
The problem is that they're expensive, typically $200 for the PLX based cards.
Asmedia based cards are slightly cheaper, but I tried those and they didn't work. So my only other hope would be a PLX card.
There are much cheaper PLX cards overseas (with cables instead of m.2), but returns could be a problem if it doesn't work.
Thankfully I had a friend who had one of the m.2 PLX cards and he let me borrow it.

Wonderful news!
IT WORKS! :DDDD

After the Asmedia didn't work I was losing hope, but now I'm ecstatic

Already started the order for the overseas PLX card. Which was $69. It will be here mid March

Getting the exact same read/write on my NVMEs that I got without the switch in the middle, which is mighty impressive.
