Well, what can you write about a memory card much? The technical data I do not know me like this, but I can report on the practical test: The first major decision support for this purchase was the price. This card (actually you have to say "map set") has by far the best value for money. 32 GB at this price, sensational. The second consideration was the flexible application possibilities, because this card can be used as a micro-SD with adapters as SD card. And if you put the micro-SD card with the adapter in the included reader has got some a 32GB USB flash drive. So you have 4 parts in a Micro-SD card, SD card, USB flash drive and card reader. As already mentioned, I am familiar with the technical data is not so, but in all devices, where I have this card so far had used (different MP3 or MP4 player, digital SLR camera, cell phone and as a memory for data transfer) I super results. The data were read and written very quickly. All devices have the card properly recognized and processed. The shipping was super fast and everything was very well packaged.
I highly recommend this set only recommend to all !!!
