Very adequate

Major consumer of SD cards, I am very attentive to the speed and reliability of all, and I inquire before buying. In particular, I am using Sandisk extrem pro at 95MB / s and 45mb / s, and I also have two Transcend 32GB 600x such as these that I use a Nikon D7000 and Sony nex 3n.
Let's be clear: I have never felt that my performance devices were constrained by this card, it is quite sufficient for my use of "connoisseur and demanding." No difference in Logging on my hard drive storage (so simple reading), such that with the sandisk. The extrem pro has for her a more robust and thus more reassuring construction ... but is it worth more than 2 times the price difference? See for yourself :)
