something i found from some guy's comments in amazon
comparison between some Komputerbay brand class 6 and sandisk class 4.
http://www.amazon.co.uk/product-reviews/B003ZTCBZ0looks like the kingmax i bought still beats the others at sequential read and random read speeds as well.
its the random write speeds that i am worried about...
For Komputerbay Class 6 microSD 32GB:
