X570 Taichi--Setting up an SSD Raid

Hi all, putting together my X570 Taichi system, and I am looking for help to set up a RAID 0 on 2 Samsung 840 pro (500gb).

New to Asrock, new to RAID arrays, but been building PCs since before the turn of the century.


Hardware:
Asrock Taichi X570 bios 2.10
Ryzen 3900X
2x16gb G.Skill TridentZ Samsung B-dies
Nvidia GTX 980 Ti (in PCI slot #1)
Corsair HX750

The hard drives:
Main drive (Windows 10): Intel Optane 905p 960gb in PCI slot #3

Others:
Intel 660p (2Tb) in M2_1
Samsung Evo 860 (1Tb) in M2_2
Samsung 840pro #1 (500gb) in Sata3_7
Samsung 840pro #2 (500gb) in Sata3_8
Seagate Barracuda pro 8Tb in Sata3_4


I am testing out/benchmarking the various hard drives listed, so any of these drives can be moved or removed except for the Windows drive.


I want to set up a RAID 0 with the 2 Samsung 840 pros.




Here is what I have done so far:

I have gone into the bios and changed Storage configuration to RAID.
As you can see all my hard drives are listed there:









But when I go into the RAIDXpert2 section, the -Create Array- section is greyed out and non-selectable.








Next I installed RAIDXpert2 (downloaded from AMD website, ver 9.2.0.127).
I encountered the problem where the Submit button is grayed out.
As per this post here:
https://community.amd.com/thread/214160
I went into the device manager and pointed the updated drivers to drivers I downloaded from the AMD website (9.2.0.127).
Submit is now selectable.

When I enter the RAIDXpert2 software, I can see my 2 Samsung 840 pro?™s.







When I choose the Create a New Array option, no drives are selectable.






I appreciate any help with setting up RAID 0 on these 2 SATA SSD Samsung 840pros.

I feel like there is some obvious step or simple task that I am not doing because I'm new to RAID arrays.

My next step is to eliminate the NVME drives, maybe there is some sort of conflict?

Thanks for reading and answering--you were right in your thought process.

Here's what I did to get it to work!

First of all, there were simple volumes and partitions on the Samsung 840 pros. I was benchmarking them as non-raid.

So I removed the partition, then I removed the recovery partitions.

Then in the Windows Software RaidXpert2, I went to the Disk-->Initialize and initialized both disks.

After which they now appeared as selectable in the Create Array menu, so I was able to create the array.

I can post my basic results once I compile my data if anyone is curious.

Thanks!

Ok! Here are some AS-SSD results:
