My Motherboard is Asus Prime Z790-P WiFi D4.
It has Built in Intel RST Raid.
I have Created a Stripe Array from the three M.2 Disks ( in the Bios ).
I have Installed Fedore 39 Cinnamon Onto This Array.
During the Installation of Fedora 39 it was able to Detect The three M.2 Disks as One Raid Drive.
And it never had any hickups letting me Install on this System.
The Installation Completed without any hickups.
And Fedora is Working Just Fine, Infact it Appears to be Very Fast and Responsive.
However what puzzles me ,is Fedora Actually Working in Raid.????.
Comming from Windows PC's , I am Used to Using Raid and in particular Intel RST Raid.
And I know that to get the full benefit of Intel RST you have to Install Intels Custom Drivers.
During the Install of Fedora onto the Intel Raid Volume, I was'nt asked to provide any Preinstall Drivers.
And After the Install, Fedora never asked me to Install any other Drivers for the Raid.
I can only Assume Two things at this stage, Fedora has Builtin Capabilities of Handling Intel RST.
Or My system is just working in Standard Mode, Ignoring The Raid Controller.
In Fedora ( DISKS ) Shows The Three 250gb Drives.
In Computer, Nemo 5.8.5 , Shows The Contents of Complete O/S as One 750gb Drive.
At the end of the day , I can say I am happy with the Speed of the System.
But it just Puzzles me as to what ( if any ) is happening with the Raid.???.

Open a terminal and post this output (for a start).

I have attached a screen shot, good luck if you can find it, because i can't see where it was placed

By the way, I do make Backups.???

Good for you - not enough people do.
That is simply my sigline; a reminder to everyone who reads it to do backups.

The RAID looks in use - let's see this (just copy-paste it here).Edit: hmmm - that looks like an incomplete listing; maybe the RST RAID is not working as desired..

cat /proc/mdstat
Personalities : [raid0]
md126 : active raid0 nvme0n1[2] nvme1n1[1] nvme2n1[0]
732588032 blocks super external:/md127/0 128k chunks

md127 : inactive nvme1n1[2](S) nvme2n1[1](S) nvme0n1[0](S)

Thanks for your advise and sugestions eveyone.
I have decided to switch over to one drive with a standard install.
