Review on TGBYHN 1TB Digital Series SDXC UHS-II Memory Card by Micheal Looney

The cards are of advertised capacity but are a poor substitute for v90 speed. In the trial test I see about 20% of the promised speed. (In other words, about 1/5 faster than the item's stats.) If you're looking for a medium-sized but fairly slow card, this might be the one for you. Otherwise skip it. Unfortunately I need the promised full speed. (I leave the map to other, slower cameras.)
