I'm not a heavy user of data but enough that my pictures and music videos wouldn't fit on the factory 4 gig card. You can never have enough memory as it gets used up quick. It has the advertised memory capacity rating and has improved speed on my smartphone and tablet when moving pictures and videos to different folders. No lag compared to the cheap factory memory card. Buy the better card the first time, you won't be regretting it later. Would recommend and buy again
