Well, since I first ordered a ADATA, but has not shipped by the seller after 5 days still, I have stoniert again and the Lexar Class 6 evening ordered the same. Received 2 days later and tried the same.
Write speed was on average 9.4
Reading speed unfortunately "only" 14.7
but I realize significant differences to the old Class 2 card. White now not which values for a Class 6 card are normal, but since this was only about 6 euros more expensive than a Sandisk 16GB Class 2 and fast enough to 720p videos play smoothly and turn I am completely satisfied.
