Lx patriot cards suck so much a55 it is not funny. i have had 2 16GB LX patriot cards suddenly die without warning taking all my photos with them. They claim to be class 10, and for R/W large files they do perform in that range however for everything else they are sh|t3. I can only assume they have used some kind of hax trickery to achieve the numbers they advertise at the cost of stability and quality. tl;dr, LX patriot uSD are worthless.
