One of the boards on my list for an Unraid build is the ASRock N100M as a low-power option.
Now, it doesn't have a lot of SATA ports, but you can expand it with various controller cards and M.2 adapters.
One of the M.2 slots is a Key E at PCIe 3.0 x1, usually meant for WiFi/BT, so I figured I could just add an M.2 Key A+E 2-port SATA adapter in there, e.g. this one:
(JMB582 chipset; should work on Unraid.)
However, in the motherboard specifications it says this:
My question now is, if this CNVio restriction prohibits me from using this M.2 Key E slot for a 2-port SATA adapter. Anyone who knows? Thank you in advance.

However, in the motherboard specifications it says this:
and1 x M.2 Socket (Key E), supports type 2230 Intel® CNVio (Integrated WiFi/BT)**
Now this is obviously about which kind of WiFi modules you can put into this slot: they have to be CNVio modules, with the signal handled by the CPU afaik, not regular PCIe modules.** M.2 PCI Express module is not supported
My question now is, if this CNVio restriction prohibits me from using this M.2 Key E slot for a 2-port SATA adapter. Anyone who knows? Thank you in advance.
