Unable to create bootable RAID 0 with 2 X 1TB Blue 3d NAND



The disks are visible in the boot sequence area of my BIOS (Asus Maximus VIII Hero - Z170, fully updated) but not in the IRST section. If I boot into windows (10 Pro 64bit), the are visible in WD dashboard, and disk management, but not in IRST (latest version). I have tried formatting in windows, and with g-parted, initializing, erasing, creating the array in disk management, creating the array in Storage spaces. I am at a complete loss.

Any help would be appreciated.

Many thanks
