because I keep seeing this mentioned, a class 6 card is most likely not going to give you the best performance for android. It has high throughput, but Android has more random read/write. Class 6 cards are optimized for throughput at the expense of poorer random read/write.

Is a Class 10 better? natemcnutty, I know you're working on the NAND boot; is there likely going to be a working version with the user file system (data.img) resident in NAND instead of the SD card? That will make stuff run a lot faster. |
don't want to derail the thread too much, but class 10 cards are sometimes 2 bit per cell rather than 3 bit per cell memory which can be dramatically faster in both sustained throughput and random read/write, but there are some class 10 cards that are only optimized for throughput and really really suck at random read/write.
Luckily, for 3d, we are limited by drivers and not by the sd card. Also, we have a user who has moved everything to nand (he was seeing if he could brick his device, but it ended up working!). He reported significant performance differences and said he would post more details later
