If you setup RAID in RST BIOS, RST hides NVME drivers from system (due PCIE-to-SATA remap), only RST driver needed. But if you want to setup RAID from Windows, you should first install NVME, then RST.
Thanks for the reply JFFulcrum! I'm new to this forum (and forums in general). It seems like it is up to me to mark your answer as correct, and so I did.
Out of my own curiosity, if you know of any resources that discuss your answer in further detail, please let me know.
Thanks greatly for your time!
