Oh well, I should have bought a slower card. At least it won't be a limiting factor. I'll compare speeds I get with your 3M bytes/sec. anyway.
I was meaning 12 megabits /sec.... By 12MB/s I was referencing what I see here http://en.wikipedia.org/wiki/Secure_Digital_card#Speeds 12MB/s is not in the table shown in that link however I am about to receive a 4G 80x or 12MB/s card in the mail .
