Hi, I wonder if someone can point me in the right direction of which Micro SDHC card & class (i.e 2, 4, 6 or 10) I should get to replace my current Samsung 8 GB Class 2 card. As this card keep un-mounting itself repeatedly. And I would like to have some more space. I have looked on google etc.. but I have ended up even more confused as some people say you should stick with a Class 2 card, while others suggest going to a Class 10 card. I am looking to get storage of 32gb, and think I will go for a Sandisk card, but its just the Class I am not sure about. (i've just found this one SanDisk microSDHC 32GB Card: Amazon.co.uk: Computers & Accessories on Amazon would this be OK?) If someone can confirm which one to go with it would be much appreciated. BTW. my phone is the HTC Sensation.
