Re:Raspberry Pi microSD card performance comparison

If I'm remembering correctly, the Pi's SD reader runs at 50MHz, doing 4-bit transfers, and not using any of the UHS signaling methods, because those use 1.8V signals that the Pi isn't set up to use for SD.

But...which card is faster in a USB3 UHS-III transfer isn't useful information for a Raspberry Pi benchmark. It would certainly tell you which cards are faster, but the info wouldn't be directly applicable to what the tests are trying to measure.
