I was planning a PC build using one of the new Z270 boards later this year. I was planning to use an M.2 SSDs because they seem like the hot tech (literally) for fast PCs. I was heartened to see companies new motherboard attempting thermal solutions for M.2 because discussions about thermal throttling on M.2s were ragging last year . Yet, after seeing the video below I am thinking that any new M.2 solutions on the motherboards needs some extensive testing.
As needs to be pointed out again, the motherboard is likely FINE. The video is suggesting using that shield is a bad idea. I hope that there will be some testing sites that start testing M.2 solutions very extensively. At the very least all these new motherboards, with more M.2 postilion or shields, need to be tested specifically for m.2 performance.
Aside for this MSI board, I wonder what ASUS TUF board does to its M.2s since they cover them up.
