Asus Maximus Z890 Extreme - Where should I install my three M2 SSD PCIEX4?

[Zbigniew]

(What I'm talking about is getting the best data transfers, Without losing GPU speed 16x). Configutation/
Processor Ultra 285K / GPU RTX 3070ti / Motherboard Asus Maximus Z890 Extreme.
The board has 6 m2 slots with the following markings:
M2_1 (Socket3) / M2_2 (Socket3) / M2_3 (Socket3) / M2_4 (Socket3) + 2x socket M2 Q-DImm ROG Slot
Alternatively, I also have a ready-to-use PCIEX4->M2 expansion card ready to be installed in PCIEX16(G5_2)
(In my case, PCIEX4 (G4) is intended for the Soundblaster AE-7.)
The answer to this question will certainly be useful for many users.

Hello. 

I installed my system drive in M.2_1, another drive in M.2_2 (top two just under the cpu) and two more in the DIMM.2 (the card by the memory).

I read that if you put anything in M.2_3 and M.2_4 (bottom two), then you lose bandwidth on the graphics card slot.
