This is just out of curiosity. There's a random dude saying there's more benefit in using a sysNAND CFW setup vs. using an emuMMC setup (which is obviously what I use today, keeping my sysNAND clean and my backup safe). His main points is that the sysNAND is faster (in terms of performance) and more stable when compared to the emuMMC. Not only that, he states there's a 40MB/s vs. 250MB/s difference between both (and I have no idea where he got such info) and that a sysNAND CFW setup is better for the longevity of his microSD card. I'm no specialist, but I know my way around Switch modding and I never heard any of these things being pointed out anywhere. Is there ANY performance difference between sysNAND vs. emuMMC?
