As that’s only an assumption of yours and your only point, you shouldn’t be reasoning this, should you.
Of course there’s many impacting factors beyond SD vs eMMC, but I’m obviously referring to that and ceteris paribus my statement is correct.
However, this is really getting off-topic now, and there have been more than enough other discussion threads on these topics, so please let’s not repeat, it’s all been said before.
So rather than continue chewing on this, please read on here, it’s a long term maintained summary of the state of play and even includes a link explaining that unlike you stated, SD controllers DO wear levelling.
True, but as also mentioned in my linked ZRAM post, that’s not because of flash or controller interface differences but because SSDs have a DRAM cache.
