Replying to SD card help

So I have recently started filimg more with my t3i and I get the error that the movie has stopped recording automatically. Ive been shooting at 1080p 60 fps and my sd card is a sandisk class 10 64gb with 80mb/s. I was told my problem was the low mb/s and the card could not write the info fast enougj. Any suggestions for sd cards for strictly filimg? Im fairly inexperienced so feel free to tell me if im wrong with my logic or direction.
