I seem to recall the USB bus on the RPi3 is limited to 480Mb/s, the fastest SD cards in the market are around 150MB/s, and the SDcard port on the RPi3 is below 25Mb/s.

Yes, that makes sense. The SDCard port on the pi seems to be slower than the USB bus.

I will say that I think your estimate for the USB bus on the pi is probably too high. In practice, I don't think it can do more than 250 or so.
