Thanks. Translating that to mb/s would be helpful. Knowing if a card has its class rated correctly is all that's important to me. I'm not going to compare one Class 4 card to another for minute up/down speed differences. So, there's no micro-to-mini adapter included with the N810? These little bastards are hard to find, and I don't want to pay more for a microSD card that happens to have a mini adapter bundled with it.
