I've got a gigabyte x299 ud4 pro motherboard. I have 6 SATA SSD's in RAID 0 as my current boot drive (i know it's flippin stupid that's why i bought the m.2). When I installed my new m.2 it would only boot to bios and only 2 of the 6 drives showed up. I took it out and it works fine again. I was really hoping to just put the m.2 in, clone my boot drive (raid array) over to it, boot to the m.2 and then wipe and reconfigure the raid array to something more reasonable. I'm beginning to worry that its not gonna be that easy. I mean worst case scenario I bite the bullet and buy an external drive and image the current boot drive to it, install yada yada yada. But it still doesn't really solve my problem. Is my m.2 using the SATA bandwidth or something? I don't see why it shouldn't work.
