I did not think ...

I bought this card to have a fast and reliable storage system. I was served. reliability has not been tested but be aware that the card is certified Water Proof. Moreover, when it was in hand, we feel that it is heavier than the low-end cards.
But above all, where we actually see a change is the data transfer. My camera has gained speed recording pictures, which saves me a range of 25% and more pictures in Burst. Moreover, there is no denying the transfers are still faster.
Sure, this card is expensive but there is still a justification.
