For a while now, I’m considering purchasing a m.2 NVME drive and there are a few things that bug my concerning theses drives. So, here we go:
Why are those drives always mounted directly on the mainboard? Wouldn’t some kind of cable + mounting kit (like those commonly used in conventional SATA SSDs or HDDS) be superior (more on the later) or equally fast? Or would the cables degrade the performance?
Often mainboards have two (or more) mounting options for m.2 drives which differer in the speed they provide. (Often related to the number of PCIe lanes). For example, my X370 Taichi has on 20GB/s m.2 slot near the bottom and one 30GB/s m.2 slot between GPU and CPU. So, in this regard it would be better to use the slot near the CPU. However, both CPU and GPU produce heat (not to mention a m.2 drive). So, from a heat perspective the best mounting option would be the one at the bottom, wouldn’t it. So, the best option would be the bottom slot because 20GB/s should be more than enough considering most drives are rated at around 3-3.5GB/s. Or do you think the heat would radiate to the CPU? (Keep in mind though, that I have a side intake case fan, which would blow air on the m.2 drive.
Any help would be (as usual) appreciated
