My motherboard is Gigabyte Z390 AORUS XTREME,
the only one with 10G connectivity.
My concern is if that embedded 10G eats PCIe lanes or not.
I also think the fastest available SSD (would it be Intel Optane 905p or Samsung 970 Pro) can't saturate a PCIx4 slot, so even the 3rd slot would be enough, no?
