[SOLVED] Nvme slots meaning ? Asus mobo

[apple.samsung10]

2 x M.2 Socket 3
1 x Type 22422280 supports SATA and PCie 3.0
x4 modes
1 x Type 224222110 supports PCie 3.0 x4
mode
Mobo: asus rog strix z390e


I have 970evo 250gb on the up slot, win10 running with it.

I want to buy 970evoplus 1tb, does that work full speed with the down slot ? Also if ı want,can ı run win10 on the down slot? 

I also have a 2.5 inch ssd, which port can ı use when 2 m.2 slots are running. 
(Also can my mobo support 3rd nvme from the second graphics card slot?) Thx

Yes the second, lower M.2 slot, M.2_2 will run at PCIe3.0 x4. If both M.2 drives are operating at PCIe mode, then you can use any SATA port to your choosing. I'd keep away from SATA6G_2 for good measure. Also, make sure you're on the latest BIOS for your motherboard.

First one supports NVMe (PCIe) as well as SATA mode.
Second one only NVMe mode.
Samsung 970 evo plus 1tb should work equally well in both slots.
Check MB manual to see if/which SATA ports are disabled when installing M.2 drives.
