Great post, and argument against file based blogs. But don't you think that serving blog posts from a database can be slower than simply accessing plain HTML files (think about good old HTML pages, not fetched through PHP).

I personally write my blog in plain HTML, which is totally static. Moreover, I host it myself, so I don't have any SSD to "speed up" file access, so would you think That (in my case) it'd be better for me to switch to a DB based posting ?
