I will start by saying I do not really understand the whole &#34;class&#34; rating system of these cards. This is described as class 10, which to my minor research, is pretty fast at uploading and downloading data. And it seems to me to work just fine. Didn't take very long to upload some HD movies I had on my computer that I wanted on my phone. My thought with buying this was simply this.... Why short change myself? Ill just buy the biggest(capacity) and the alleged 'fastest' and by happy. And I am.
