Hi, Putting together a simple system and i am thinking of using M.2 Samsung 980 PRO , 1 TB of memory. 1TB is certainly enough to put the system and most of my applications and still have plenty of space for my pics and other stuff. However, do you think i should get an additional 1TB like a 3.5" HD memory as well? I was also wondering how often do the M.2 memory sticks fail?
