On the net I see diferents SD  cards Class 10 models, but some cards work with 80 Mb/s, 45 Mb/s & 30 Mb/s


Here the samples

Sandisk Ultra 30 Mb/s
Sandisk Extreme 45Mb/s
Sandisk Extreme plus 80 Mb/s

Also Sandisk Extreme pro over 95 Mb/s

My question is to know the max banana pi Speed SD bus support?
