So I'm manually removing posts from my twatter account and found this pic.
This shows the full-text email search speed (in seconds) on SSD and HDD, when emails are searched in random order and sorted by physical position in folder's datafile. In this case, search speed on HDD was reduced from 527 seconds to 15, and on SSD from 41 to 11.
Non-obvious (for some of younger devs, at least) thing here is that even SSD benefits from in-order file processing because OS and SSD can provide read-ahead and SSD also has seek penalty (small, but it's still there).
