That sounds like what they call "fakeraid" using the rst controller, really there is no need to anymore. For probably 15 years now i've used two disks in a linux mdraid volume for boot/rest in raid 1 for redundancy, usually a crypt volume with luks atop the rest physical volume, and lvm atop that, with ext4/xfs atop that. Still do this with nvme disks just fine for a few generations of boxes.
I did setup my old desktop as a proxmox box with zfs doing my raid1 recently booting entirely off that (super dope, +++ for that), ymmv per distribution, but that's an option as well for handling all the software raid function as well. Ubuntu server with the deb installer always handled setting up raid/crypt/lvm/fs just fine, haven't in a while personally, but probably still does adequately. I diy normally with Arch, but it's what drives this laptop I'm typing on currently with a pair of 980pro nvme samsungs doing above.

Hi All,
Ok, I'm finally very close to being able to go to a full Linux
environment and leave the Microsoft ecosystem. I'm semi-retired
and still do some Microsoft Data Platform work (which was my
career). I recently got a Dell Latitude and put Kubtunu 22.04 on
it and managed to get all my applications, dev tools (many MS
tools too!), and hardware working. I've been down this road before
in years past and Linux on the desktop was always a "no-go" for
me. So, I was *astonished* how easy it was to install Kubuntu and
everything just worked. That's how it must feel to be a Mac
person! :)
However, one of the hurdles with the Dell was that, by default,
Dell configures the BIOS such that the boot drive (NVME in this
case) is set to be in RAID mode instead of AHCI mode, even though
there is only one drive in the system. This caused Ubuntu to
simply not boot. After doing some research I came to find the
Ubuntu doesn't support Intel Rapid Storage Technology (RST), which
RAID requires. It was a simple fix to reconfigure the BIOS into
AHCI mode, since I was going to wipe the Windows partition anyway.
But, my main production dev box is Win 10 and I have two NVME
drives in a RAID 0 (mirror) configuration (using hardware RAID in
the BIOS). If I want to install Ubuntu I need to be able to
implement this same level of RAID. If Ubuntu doesn't support the
Intel RST hardware, how can I install Ubuntu and have a RAID 0
arrangement? I'm not looking for a particular answer to the
problem just some suggestions on what to research. LVM? ZFS?
Software RAID?
Any thoughts would be appreciated.
Peter
