Question If both M.2 Slots are used do you still get full speed?

[Stormer3]

I'm going to use both M.2 Slots on this motherboard. If both M.2 Slots are filled with SAMSUNG 970 EVO PLUS 1TB drives will they both get full speed?

I haven't ever heard of m.2 sharing the same lanes so both should be at the full x4, someone else can jump in if I'm wrong let me know.

Never happened in any of my builds going back to 6th gen Z170 boards

Full speed on both but you will lose sata ports 5 & 6 according to pg 32 of your manual.
