@Geoff might be interested in this one - my Lexar 2933x 64GB XQD used in the Lexar XQD card reader on USB 3.0. Seems it might be reading/writing at 440MB/s inside the D500, but it's not doing it when connected to the PC by USB 3.0. Still very quick though!
Here are the results for the SD cards I use.
SanDisk Extreme PRO 95MB/s SDXC 64GB which I use in the D500's SD slot as a backup for the XQD:
SanDisk Extreme 45MB/s SDHC 32GB which I use/used in the D3200 (only a single slot in that camera):
I also occasionally use/used a 16GB version of that same Extreme 45MB/s card.
