I currently have standard 2.5 SSDs but have decided to try moving to m.2 instead. I know the Ultra M.2 supports the NVME M Key, and unless I am mistaken this board will only boot to NVME m.2 drives. With that, my query moves down to the 2nd slot and if it is compatible with the B & M Key m.2s such as the Western Digital Blue 1TB. To be honest I wouldn't mind if the top m.2 would support and boot to this form of m.2 as it is the most common and relatively cheap right now.

Any help is appreciated.

Thank you!

I found my answer after looking through much older forum posts. The top m.2 only supports PCIe (NVME) chips. The bottom can support the SATA3 m.2s without issue.
