    Will the tablet take advantage of a 80mbs card or should I save my money and get a 30mbs card?

    what is the price difference of the cards that you're thinking to buy? If not that much always go with a faster card

    Twice. Just want to know if the note pro supports those speeds.

    I'm not into scientific tests but based on my experience with my 64gb Sandisk Extreme Plus yes it does support it. File transfers over USB 3.0 on a PC are as quick to external card to the internal memory.

    Bottom line, get a cheap class 10 card and not a UHS-1 80+mbs one as it appears the Note Pro does not support UHS-1.

    I tried benchmarks on both the Note and a PC as well as copying a 1 gig file over USB3 to both a card reader and the Note. As you can see it's slow and a cheap class 6 or 10 card should be more than enough.

    Sandisk 64g class 10 UHS-1 rated at 80mbs - card connected via USB3 to PC, 93mbs read, 61mbs write 500k sequential
    Sandisk 64g class 10 UHS-1 rated at 80mbs - 19.2 read and 15.2 write using AT SD default test
    Sandisk class 6 16g card in Note Pro. 17.4 read and 10.97 write using AT SD default test

    Sandisk 64g class 10 UHS-1 rated at 80mbs - copy 1g file USB3 to card reader - 28 seconds
    Sandisk 64g class 10 UHS-1 rated at 80mbs - copy 1g file to tablet (usb3 connection) - 1:28

    Digging up this thread because right around the time it was still active (4/2) is when I lost my original Note Pro. I had wanted to respond with test numbers but I couldn't without a unit in hand.

    I've got my new Note Pro now and a couple of microSD cards to test and have concluded as I had described earlier in post #6 that the speed of the microSD card does make a difference when one moves up to the higher end cards.

    In comparing a Sandisk Extreme Plus microSD to a Sandisk Ultra microSD I can confirm that the transfer speed to the Ultra is limited by the speed of the card. USB 3.0 vs 2.0 cable use makes no difference. However, with the Extreme Plus microSD card not only is transfer speed to the card faster than the Ultra but there's a slight yet measurable difference between USB 3.0 and 2.0 transfer speed to the card as well.

    Details here.

    I make no claims to this being accurate testing, it is simply myself testing file transfer times using a stop watch.
