I tested it ... but I can't find my results. Its a very good card.I looked again, I also have a Samsung SD in my SPro (this one http://www.amazon.de/Samsung-microSDXC-Class-Speicherkarte-MB-MGCGBEU/dp/B009HPFUGI) .. The SanDisk is then in my phone.
Is the write-speed as fast as advertised? I thought about buying one of these cards..
