BTW, I added a speed test I did using an old USB 2.0 flash drive into the first post of this thread. As I suspected, USB 2.0 devices are just too slowdue to their specs.

Merely as a comparison, I included the speeds I got with the same external storage devices connected to my MacBook Pro 15” Retinal 2014 which has an internal 250GB SSD with USB 3.0 USB ports. I tested the internal SSD on the MacBook Pro and it has READ/WRITE speeds of about 600MB/s for both, which is very close to the USB 3.0 specs. So far all of the READ/WRITE speeds for my external storage devices have been faster when they are used with the MacBook Pro than when used with the iPad Air 2020. Some results are fairly close on both the Mac and the iPad, but some are far apart.
