Memory card without problem. I use the cards of this mark since longemps and qalité is impeccable. It serves me in a digital camcorder HD Canon HF200, read and write without problems. Only complaint with the packaging, is sold in blister without protection case, I used two gold, one in the camcorder and one in reserve and luckily I had a case of a previous purchase or she would have been loose in the bag. She left when mêmeun excellent value.
