What do places like Starbucks use?
"Places like Starbucks" is pretty vague, so I'll address categories independently.
Starbucks uses a Ditting for bulk grinding (i.e. - French Press), and pre-ground pouches for their Coffee Of the Day. (at least, they did when I worked there a few years ago)
For espresso, they have their SuperAutomatic espresso machines with built in grinders. Takes all of the art and 'specialty' out of the equation. I have no idea what grinders Saeco stuck in them, either.
Places that compete with Starbucks tend to use something like a Grindmaster or Bunn G3 for bulk, and something like a Mazzer SuperJolly, or Rossi RR45 for espresso.
Places that see Starbucks as no competition use things like Mazzer Roburs, or Anfim Super Caimano , or Malkhonig K30(or K60), or a Kompak K10 conical. Everyone has their preference of what they like, based on grind speed, cup quality, and efficiency (i.e. - cleanliness, accuracy when dosing, etc..) They also tend to use Ditting or Malkhonig bulk grinders for things like chemex, french press, siphon, or auto-drip.
Big bucks, those. The closest thing to any of them that I have seen in this thread has been the doserless MACAP picture up there.
For home use, I have a Super Jolly for espresso that doubles as use for other brew methods (for its grind quality). You can swing these on e-bay for pretty cheap sometimes. (pretty cheap meaning <$300)
It used to be an industry standard, but time marches on, and so does innovation and technology.
