Performance with each Class 10 sdcard varies some.
I also ran Antutu benchmark on my Nexus and got 13.3 MB/s write, 30.6 MB/s read.
So faster that Class 10 requirements.
If you're on a pc it reads as an MTP device, so the transfer rates are slower than a traditional usb connection.
I don't know how fast exactly the speed is as I have been using AirDroid for quite awhile now.
AirDroid is the best way to move files for sure! *Hey redstar, nice sig man!
Yeah, I liked your signature so much, I copied it.
