Unfortunately, it’s on an internal USB 2 bus, which makes SD access extreme slow. All the external USB ports are at least 3.0, so I use a slim 64GB flash drive.

I guess that probably means it's falling back to a normal SPI interface instead of the faster quad-SPI MMC interface? Maybe they don't want to spend one of their chip's QSPI peripherals on storage expansion.
