For our new digital camcorder Samsung HMX-H200 HD (1080i), I bought at the same time this card Transcend 8GB Sandisk Extreme card and HD video 8 GB (class 6). I wanted to be sure to have a functional map for our journey and some reviews on the Transcend made me doubt the quality of it ... Nothing, except the price, I did not see any difference in usage. I recommend this card turns out to be a quality / excellent price.
