An update to this thread finally... My card has started being fast again. A friend needed me to copy some files from his card to a pc so I did that, tested a copy from it (it was an 8gb class 4) and file transfers were fast. I thought I had a defective card but I put i6 backin and tried to copy a file and it copies fast now. The "fix" seemed to be remove it and put it back in again - something I havent sone since I got the card. Just something to keep in mind.
