The best high-speed SD card on the market, if you get the right products delivered !!! Having stayed a copy of Transcend 2GB 150x (model name TS2GSD150) possessed and know the performance of the card, I had ordered a second copy (MarketPlace dealer). But the slow variant TS2GSDC was delivered. For the uninitiated at first sight not to be recognized. Where also the printed Modellbezeichnug "TS2GSDC" was covered in the original packaging with a sticker. This label juggled the fast and expensive model "TS2GSD150" before. Customer deception or chance? So: Watch out! Customers report by review of a disappointing performance could probably be "wrong" card held by the !!!
