Said Name "Nope"
The class is how fast the memory is read.  This is a fast card.  There are faster out there, but they are far more expensive, and not worth that expense, in my opinion.  Does everything perfectly and in a compact package.  SanDisk is a brand name, and trusted by me.  Worth the extra buck, since I've used SanDisk since they made 8MB CF cards&#8230;how far we have come&#8230;
