[SOLVED] M.2 Raid 0 reduced iops?

Hi, I have an x570 Taichi Motherboard and 2 970 evo plus 1TB m.2 drives.

I want to populate m.2 slot 1 (direct link to cpu) & m.2 slot 2 (link to chipset)
Then I want to use motherboard to setup raid 0 with the 2 drives for 1.9TB raid 0 array.

The problem is when you do this the IOPS goes down.

Does anyone have a solution that will let me raid 0 these 2 m.2 drives without reduced iops?

Also I will not do the solution of putting a PCIe card that holds 2 m.2 drives into my slot for 2nd video card.

I am only running one GPU but the addon card will make my main gpu be x8 instead of x16.
It also kinda gets in the way of the GPU above it making it abit harder to pull in air resulting in 1-3c hotter temps during load.
 
So most of the info online shows that doing a raid 0 m.2 setup in :
  1. Through Windows
  2. Through x570 motherboard
  3. through PCIe expansion card (changes top gpu x16 slot into x8 slot)
is all a meme because you lose IOPS.

So as far as I know nobody is doing this and it's a joke.

Some people have basically said you are an idiot if you raid m.2's so are they correct?

Does anyone have information to show that between 2017ish to right now mid 2020
that there is a way to raid 0 m.2 to get increased read/writes without affecting iops or better yet increasing them as well.

Thank You.
 
I wouldn't put it in such an insulting way, but there's very little reason to use m.2 drives in RAID. RAID was created in the 1970s when drives were much slower and large hard drives very expensive. At these disk speeds, there's no real advantage to RAID.

The consumer use case for RAID is for people who are running servers and things such as storefronts. In those situations, uptime is crucially important. Same goes for workstations in which time is literally money.

If time isn't mission-critical, there's really no purpose to RAID at the consumer level. They're not faster in any meaningful sense and RAID is also not a backup solution. For 99% of home users. Simply having a good daily backup in a normal way is much more efficient -- and far less risky -- than messing around with RAID. I used to play with RAID a very long time ago, but I haven't seen a point for long time.
