DAMN we are all limited in Speed!

So in short, i own minix u9-h.

I decided to buy a expensive Sd card Sandisk Extreme. First i thought fast one is always better.

As you can see Coreelec does not give us the full speed of this card.

Specs of Sd as i expected it would be in Coreelec:

160 Mb/s in read and 60 Mb/s in write.

But you can see in picture Coreelec throttle us.

Is that true ? i had the exact same result with my cheaper card.
