Some time ago, this was important to decipher the marketing behind MongoDB. Their benchmarks ran with a loose isolation (read_uncommitted iirc) that didn't guarantee a durable flush, and they'd benchmark against defaults from postgres, etc, which didn't use this isolation.
Clearly it worked for them, but I spent a few different stints cleaning up after developers who didn't know this sort of thing.
