On my D600 with UHS-I interface the card runs really well. When speed measurement on the PC with USB 3 they came to 30 to 35 MB when writing. Indicated are up to 45 MB writing. The read statement with 94 MB I find a bit misleading, because Panasonic as card has read the 90 MB and 80 write. But the card was for the price of about 36 euro fine.
