Hello Guys am planning to buy a new SD Card For my Lumia, As Windows phone 8.1 allows us to install apps on External Memory, Can a Class 6 SD card Can Handle those applications to be installed on that Card???

Will there be any Limits, Or should i go with a class 10 SD Card??

Hi Asik,
a class 6 mean 6MB/s, if you have a 60MB-game it means the OS need up to 10 seconds to load this game (it is not really so, but you can assume it). A class 10 mean at least 10MB/s, so you are 40% faster.
The question is: why not directly a class10 SD? If you want to be fast, it is better. If you doesn't care about 40%, a class 6 is also ok.
Normally, games are loaded in the RAM, so it is only slow to load. Once it is loaded it should be fast. But I would buy a 64GB class 10 (my favorite is Kingston) SD for 30$.

Your math isn't quite right.
games don't need to load everything at once, so I don't think you'll necessarily see such a big performance gap.

I'd wager that a Class 6 card will work decently, but as tiger says here, why not a Class 10?
