I kept reading expecting an explanation for this, but there isn't one. Does he understand the difference? Who knows.

The explanation of "every step of the build" is pretty limited too.

I do understand this but what is wrong with recommending picking up a USB 3 external drive over USB 2? I doubt the Pi is the only device it will be used with.

"I am still working on the best way to access the data without disconnecting the drive from the Raspberry Pi every time I want to add/remove something."

It sounds like he's putting the data on the USB drives from other computers, not from the RPi.
