Indeed. The summary talks about what you need to do to saturate a SSDs read and write bandwidth. I guess the post would find its audience better if the title was "What a programmer should about SSDs when optimizing IO".

I'd be more interested in the trends in SSD behaviour are. It seems SSDs have bigger and bigger DRAM caches and wear ceased to be an issue many years ago, so there's not much payoff in the write side advice of the article.
