[SOLVED] M.2 drive question

[wogfor]

I am looking at possible upgrade for the future, and of course technology has left me behind. Most modern motherboards now support M.2 drives. I only recently joined the new age with an SSD connected to a SATA port in my gaming rig built a few years back.
Is there a decent tutorial to help me understand different types and how to match them to a motherboard? A few sites I looked at seem to focus on laptops.
I picked a random board as an example : ASUS Prime X470-Pro. It lists several numbers for the M.2 socket but also has SATA express?
Thanks

Yes check out this guide - https://www.velocitymicro.com/blog/nvme-vs-m-2-vs-sata-whats-the-difference/

Some really useful information there

The numbers relating to M.2 are size, basically think of it as small, medium and large (length not capacity). That particular board accepts all these sizes listed.

This is all you need to know...

> M2 drives are usually of two types, SATA and NVME.
> NVME drives are way faster than SATA drives.
> Most modern boards usually have two M2 slots.
> M2_1 is usually direct to CPU and M2_2 is usually direct to chipset.
> On some boards, the M2 slots share bandwidth with chipset bus lanes.
