I am not so in-depth in low-level hardware, so I’m wandering - is it possible with m2->pcie x4 riser (e.g.)
and pcie->8 sata card (e.g.)
get use of all ports available on this card? Could be there some driver trick or another incompatibility?
First of all, is M.2 port on RockPi is real PCI.e x4 slot?
Have a nice day and thanks
