The many - partly inappropriate critical - reviews I would like to join nor this "bludgeoning !. As says the carpenter: measure can be only when the ruler is long enough ... With the right computer / reader combination the SAMSUNG cards provide the values indicated by the manufacturer - which are not outstanding, but achieved stable (10.5 / 20) - see the photos under AJA test for 32GB version (Class 10 ) above. The special thing about the card is in my view the robustness, especially the water resistance. I know a map, in particular in the "normal" price regions that could keep up. So do not complain about the last ounce of performance (especially when it may be due to its own hardware ...), but think about what you want / need. Who only "quick, quick" wants somewhere better place cards, who "accident suitable" looking card for everyday life one will find suitable. For me it's in multiple copies of both the photo and video in the pockets - even the fastest videocams (my SONY works with 28Mbit / s) only need Class 4 ... and who already makes 5x a day 143 continuous shooting at 10 frames / s?
Supplement for 16GB version: Mutatis mutandis, the above statements apply. The 16GB card reached 10.0 / 19.7, the performance of almost 32GB, so you could even pass as Class 10 - SAMSUNG they offered a fair manner as Class 6, which surpasses effortlessly far. Almost Class 10 performance, superior ruggedness, 5-year warranty from the manufacturer brand and a price of less than one euro / GB - what more could you want ?!
