Z390 Extreme 4 m.2 and Sata drives

In another post I read "Regarding your question, only
the SATA type M.2 connects to M2_1 will disable the SATA3_1 port.


If you are using the PCIe NVMe type M.2 at M2_1, all 4 SATA ports can be used."
====================



Hi, I have a Z390 Extreme 4
I tried to install a 970 EVI NVMe M.2 at M 2_1 and M 2_2

Both times other Sata drives were disabled.

I thought if it was an NVMe it would not disable.

Any thoughts, any way to get all the drives to work?
Thanks

Are both port capable of the same speed ? (i.e. PCIe Gen3 x4) or is it one with this speed and the other one with SATA3 only ?

I'm trying to see if it's interesting to make a raid 0 with these 2 ports.

Thanks !
