Also just a note - good class 4 card is best choice for N900 - much better than class 6 and class 10. The latter (6 and 10) have faster bulk write/read speeds, but much lower random access/write and small parts handling. As a result, class 4 card makes device fly with swap set on it (and disabled on eMMC).

Of course, all this "class" thing is very arbitrary (no true standards), that's why I've said "good". Sandisk is known for great class 4 cards.

Personally, I'm using class 2 card (yet, using swap on it exclusively, still makes device fly), but in case of upgrade, I'm definitely going to use class 4 card.
