Flott arrived, packaged appropriately - now in my laptop and c't h2testw started. The results were pretty sad: ~ 20Mb write / read 20Mb. Can it be because of my card reader? Hardly, because I have already calculated a Qumox before 2-3 Jaren from England ordered with 64GB. This old card I earn through ~ 34 / 45Mb speed in the same reader / Laptop.
To be fair, we must say that Class 10 is adhered to anyway, but it is 3-4 times slower than the speed recruited. So for the price of just 40 Euro still passable, although you need for sequential shots at approximately 6 per second in RAW + JPEG image per average 35MB and it makes what!
Card inserted in my d3300 - prompt the message was something like "This card is damaged, please insert another ...".
And d3300 is pretty much the latest "compact" -DSLR made by Nikon, as of July 2014. The map therefore completely unusable for me. Wanted to format the card, the camera did not allow the manipulation.
The third chance was given the card in my mirrorless Lumix GF3 - there immediately came the message that the card was inappropriate and possibly might not be fast enough for filming ...
Unique compatibility issues - namely card showed no R / W error, but was only a 20/20 and 60/80 stat is for the very purpose - to avoid. If returned, thanks to Amazon.
