OK I have narrowed my choices to
Samsung 32gb class 10 micro sd/ sdhc
Lexar 32gb class 10 micro sd/ sdhc
Sandisk 32gb ultra class 6.. micro sd/sdhc
Transcend 32gb class 10 ultimate
So I know nothing about how good a sd card is. Anyone help me out choosing 1 of these
If you're flush then I'd splash out on http://www.7dayshop.com/catalog/prod...ucts_id=113599 (Sandisk Mobile Ultra Micro Secure Digital (MicroSDXC) Memory Card - 64GB - 200x (30MB/s) With Adapter). The specs claim that this could be up to 3x faster than any of the list you've got there, and the GS3 specs state SDXC compatible.
Apart from that, I'd drop that Sandisk off of my list (unless it's cheap) and go for a class 10 card. When it comes to storage I've never found the saying "get the largest amount of the fastest you can afford" to be wrong. I "upgraded" my old Transformer tablet to a 32GB Class 10 card in August of last year and it was worthwhile (although it was only a little bit cheaper than the price that 7ds above are doing the uSDXC card for - that's progress I guess! )
