I think that micro SD card Class 10 U3 guarantees minimum 30MB/s. So it supports even 4K recording...
But I still don't know if it is worth of a lot of money. If benchmarks are true - Tab S has UHS (your 45MB/s). If!
According to Samsung support, the Tab S micro SD speeds is limited by the USB 2.0 bus, or 60 MB/s. So that would imply UHS, though the 90MB/s cards would not get the full speed. I would like to see someone test a 90MB/s card and see what the results are. Probably just going to go with a 48MB/s card if there isn't any difference. Though I think write speeds are significantly different between the higher speed UHS-I cards and the lower speed ones (50 vs 10 MB/s write I think).
If anyone has a couple cards and a Tab S they can test with, I would love to see the results.
