In my experience designing these things, 1-2 hours only provides enough time for very simple assignments, which aren't enough to actually inform the reviewer much at all about you as an individual.
It's hard to get one at 4 hours, but that provides just enough to really see something while still being respectful of candidates' time.
Of course, this is entirely dependant on the type of programming that you're hiring for!
