[Request] How to use 4 NVME drives raid 5 as OS

Now moved to correct section

AFAIU, this is not possible on T7910 without something like Broadcom MegaRAID 9560. And you would have to use some sticky tape to fix your NVME drives somewhere.
NVME Firmware-RAID is available since Skylake or so (there are many compatibility considerations) - this is called “Intel VROC”.
T7910 got older chipset&CPU.
I’d also say that NVME RAID doesn’t make much sense for OS drive, in terms of performance&reliability.
And your question is hardly related to this topic.

@microhunt :
Welcome to the Win-RAID Forum!
Since I neither ever had a Dell PC nor tried to create an Intel RAID5 array consisting of NVMe SSDs, I cannot help you, but I agree with i3v: The benefit of such RAID array may bot be worth the effort to get it properly created and working.
