Sealed bearings are the same tapered roller bearings as non-sealed bearings, just not serviceable. They typically go 100k or so before replacement so that gives you an idea how far serviceable bearings will probably go if you never touch them. BTW, I have pressed a set of sealed bearings apart and there wasn't very much grease inside.

Actually I have a pretty good idea about how long sealed bearings last. I've had a fair share of vehicles in my life and lots with sealed bearings. I've only ever had to replace sealed bearings on RAMs. Both trucks were third generation RAMs and needed to have their front hub bearings replaced right around 100k. A common issue for that generation of trucks.
I haven't had a sealed bearing fail on a Honda, Nissan, Hyundai, Kia, Ford, or Chevy vehicle. They were all sold between 150k-200k with their original bearings intact.
