some consumer drives lie about when the data has actually been written to disk (making write barriers ineffective), in those cases the OS will send more writes to the drive and the drive will go ahead and re-order them with the other writes that are in it's buffer.

And as someone else pointed out drives these days seem to have up to 64MB write buffers so that could be a lot of corruption if that data goes missing in-flight when the OS was told that it was permanently committed.
