I bought this 16 GB card, because I (San Francisco Orange) wanted to have a microSD for my smartphone. It fit in there up to 32 GB. However, the 32 GB MicroSDs times as expensive as this card at the moment in the best case 3. In addition, these 3 times as expensive cards with 32GB provide only half the reading speed of this card.
The positive reviews have purchase course influenced me
== == For Performance
To put it straight to the point, I've tested with the program "SD Tools" for Android on my Smartphone. Although I tested with my laptop, which has Ubuntu running, but I could with a simple, manual copying thus obtain better results.
Read Speed Write Speed
19 MB / s 5 MB / s
Although the speed is not as hoped for by other reviews, but still better than most other Mirco SDs have this capacity and to the card is still very low. So I'm not disappointed. Writes are in smartphones eh not so important. The read speed is because look more important especially with movies or App2SD.
Conclusion:
I am satisfied with the purchase and would make it again.
