Hi friends, few days back I brought samsung evo class 10 ( UHV 1) 64GB sd card for my asus zenfone. company gaurantee 48mbps read speed and 16mbps write.
But when I tested its torally crap. I used card reader with usb 3.0 port to check status. What I found is 100 to 200kbps speed. Its take almost an hour to copy 1gb data. I recommend go for scandisk instead of samsung if you are looking for 64gb sd card.
