Does it matter if you use a cheap SD card or a more expensive high end one. I just bought a 128gb 10 class sd card for $7 on the Internet and was wondering if it matters that I use this card. Is it better to use a more known brand like a 10 class more high end card from Sandisk. My main concern is that the quality of the video will be affected. Does the quality do the sd card (cheap card) produce more grainer or less quality images than the more expensive one if they are both class 10?
