As far as i known the differnce between this one and the first one in your photo is the sticker, one says class 6 while this one is class 10 but they have the same speed.
The first one has the "I" that indicates UHS-1, and is likely faster. Ie. it may actually achieve the 30MB/s. Whereas a non-UHS-1 card probably wouldn't.
My UHS-1 cards all top out around 20MB/s in a non-UHS-1 card reader, even though they go to 50MB/s+ in newer readers.
I wonder how a card can claim 30MB/s but not be UHS-1 ...
