I give this card SDHC 4GB 5 points because the card while the Class 4 corresponds, however, has proven itself in our high-quality camcorder with true full HD at full utilization. I had 8 GB cards abschalteten another company with class 6 The repeatedly as they could not meet the reading speed requirements. (Buyer although I had said for a camcorder, but the camcorder is not C ...., our needs certainly normally at least Class 8)
