I'm new to M.2 SSDs / how to set it up?

Hey,

I just got my first M.2 SSD (Samsung 970 Pro) ever and installed it on my Z370-F. BIOS seems to recognize it and set it to PCIe x2. In Windows 10 when I open Disk Management it says something about initialization and lets me choose between MBR and GPT. I'm lost. 😄

Do I need to change something in the BIOS and how do I need to configure Windows? Thanks in advance.

select gpt and then assign it a letter, windows tells you exactly what to do, what's so puzzling about it? btw if you need hardware encryption feature of samsung it won't work as asus doesn;t bother updating their bios so you-ll have to stick with software encryption

OK, thanks. And how about the BIOS? Is there anything I need to tweak?

Secure boot = on
Compatibility support module = off

this enables you to use UEFI boot (GPT) instead of Legacy boot (MBR).

no siggy, saw stuff that made me sad.

Thanks, that's good to know. How about the PCIe mode for M.2? Should I leave it at x2 or change to x4?

my first instincts is to leave it to [Auto].
granted, i'm not too familiar with your system; and also, intel is notoriously stingy with their PCI-e lanes... so...

i say: #yolo and x4 it, and see what happens. if something borks up, set it back to x2.

[Auto] isn't an option from what i can tell. I set it to x4 and so far it seems to work.

Thanks again for all the help.
