I just recently upgraded my computer. Buying the b450 aorus pro WiFi, a couple other components and WD Blue m.2 2280 ssd. I installed all the drivers with driver easy and the ssd is not showing up in disk manager. Not too sure how to operate the bios but I read some other posts along the same lines and it seems I could not find it there either.
Note: I put the ssd in the bottom m.2 slot because the top one was too long being 110 and the ssd was only 80
