Block transfer sizes over about 64kB are totally irrelevant for 99% of all people. Don't even bother testing anything more. Yes, bigger transfers happen, but a lot of common loads have *smaller* transfers than 64kB. So benchmarks that try to find "theoretical throughput" by just making big transfers should just be banned. They give numbers, yes, but the numbers are pointless.
