F6 drivers are required for INTEL RST Raid. The built into windows AHCI driver does NOT support raid, nvme PCI-E or Optane cache. [URL]   [URL] [URL]      
Hi .. thx all for being so helpful all these years. I’ve a new R 11  3090 coming with i9 / 10 series kf. The storage drives are my question. It should arrive with the m2 2 tv.. and the 2 tv  7200 rpm HD’s. So I see in forum that this should leave the 2 ssd slots empty for me to install 2 crucial ssds. question is that are they like my Area-51 R2 and 2 drives of equal size will add together in simple raid. This is what I hope for.  
Aurora R11 is coming, SSD slot question
