[SOLVED] AMD-RAID on Linux: rcraid. Is it working with NVME disk?

[Stanley83]

Hello to all.
I've a new X570-based system with 2*1TB NVME SSD configured in BIOS as an AMD-RAID (zero).
I successfully installed Windows on it providing the RAID drivers at setup time.

My plan would be install Linux (Mint) alongside Windows on the same system: using the Mint live USB i cannot see any Raid array but only two separate NVME disks.
I tried to google for my problem and found this URL: thopiekar/rcraid-dkms: AMD RAIDXpert driver as DKMS package where a very kind programmer created a PPA for Linux with drivers by AMD, modified to work on younger chipset and kernels.

I installed these drivers by PPA into the live Mint but, even if the module is installed and loaded correctly, I still cannot see any AMD-RAID device

The situation can be easily summarized in this image.


Nobody was able to made it working?
Thank you.

The obvious question is - why? Do you think RAID 0 will give you that massive boost you expect compared to non-RAID drive?

I've been in that business quite a while to have one simple rule of the thumb: Never install OS on a drive needing additional drivers. Learnt that from AHA1542 times...

2x 1TB NVMe in RAID 0 as the OS drive?
Why, in the name of FSM, would you do this?

What specific benefit do you hope to gain? What do you use this system for?

And now want to dualboot Linux on that same array?
No.

Thanks for suggestions.
The aim is to get the maximum performance obviously... regardless the real benefit... and yes, I want to dual boot from that array. I did it in my past systems with success.
I read the raid manual that the NVME raid is not supported by the mentioned kernel module (just SATA raid seems working) so Linux will run on a VM until a kernel module will be available.

2x NVMe + RAID 0 can be slower than individual drives. At best, no user facing gain.

If it were a slamdunk as a performance boost, we'd all be doing it.
