Thank you!  However your message illustrates the way in which Apple II is closed. What is the disk drive speed?! Look at wiki articles for 1541 or 1551 Commodore drives - they provide us with information. I looked at hundreds of lines of Apple II drives texts and found nothing! So I used book in Russian about Apple clone to find that drive rotation speed is 5 per sec. This gives theoretical maximum 1280 bytes per second and this allows to make the conclusion that speed should be close to C1551 but it is only speculation. You mentioned different drives models but... What are their speeds? It looks like a magic mystery. IBM PC compatible computers always give us tons of benchmarks...
