I suspect most people would be OK with the idea that you can only handle about 50 tracks on an external USB2 drive. The harder results to explain come from internal drives. I will definitely get my own mac mini with a spinner inside running tomorrow and re-run the test there with your additional line, and then redo the math you just did above.
Interested to hear the results, more data points.

Yep, the tests you posted confirm it’s possible. Just double your buffer size from 65536 to 131072. Half the number of seeks, and track count goes from 49 to 100.
