Sandisk Extreme 32GB U1   micro SD card

Good card, glad to know that read speed can achieve 22.3MB/sec.

Should this micro sd read at least twice of the speed, shouldn't it?! Huh

Did i missed something?

You can't exceed ~22MB/s sequential read/write speed on Pine64. But that doesn't matter that much since random I/O is way more important therefore you should choose a card that shines here. For some insights please read through this thread.
