I think I am a fast reader but since pages contain different number of words, I can't actually give an estimate. Anyway, when I have to read the same page with someone, I am usually finished and start to re-read it out of nothing to do it while they are still somewhere in the beginning of the text.
I usually read during commutes to and from work, when I have to wait in queue, when I brush my teeth, at boring conferences, etc. so I don't have time set for reading alone. For some reason I concentrate on my reading best when there's some other external stimulus at the same time. As for Harry Potter, I read each of the books 4-7 for about a day or two, but I never had a designated time for that as I was an adult when the first book was out so I had to go to work and do chores too.
Also, the comprehension level varies depending on the book. If it contains facts and figures, or if it describes action, my level of comprehension is about 100 %. If it is a management manual, however, or, God forbid, a sentimental novel, the level of comprehension is practically nonexistent (in the latter case some time after the reading I can recite passages from the text but I don't actually understand the meaning unless I force myself to it and I forget it very quickly).
Usually there's no voice in my head when I read, unless I specifically evoke it (when I read a boring text, I do need a voice in my head) - which slows things down a bit.
