    For the Gateway 3DS, is there any recommended sd card class? I know on the NDS, initially the recommended class was 6. Was wondering if that was the same, or if there was a general consensus on the class for the card.

    Generally faster is better. I've had minor lag in some games with a Class 4 on my NDS, so I personally wouldn't want lower than a 6 for 3ds, with 8 being preffered. Then again, I don't know what the bandwidth is on the 3dscart itself to know if it would be a bottleneck at any point.

    I've been able to run multiple games on a class 2 MicroSD card without any issues. Though, I did buy two class 10 MicroSD cards (SanDisk Ultra 8GB) for most of my Gateway usage.

    Out of boredom I've compared the loadtimes of a few games from a noname class 2 and a transcend class 10 (no u) with a stopwatch. I wasn't able to measure any significant difference.

    However there are noticeable differences in write speed on the computer, writing a game to the class 2 takes 4 times longer than to the class 10. Granted, in a typical use case scenario the gateway microSD is way more often read than written to, but as faster cards aren't that much more expensive I'm more than willing on spending a few extra bucks. Especially as I will most likely still be able to use those faster cards a few years down the road when the gateway and(or the 3DS went the way of the dodo.

    Pretty much echoing what's been mostly said in this thread, there is no notable benefit to using higher class micro SD card for 3DS ROMs.

    Makes sense since SD class numbers are only based on write speed, not read speed.

    True, by the SD standard the SD class ratings only guarantee minimum sustainable write speeds. But empirical evidence (I don't have any tangible numbers at the moment but did a few benchmarks some time ago) shows that read speed correlates with write speed. See for example http://www.wired.com/reviews/2013/12/highlow-sd-cards/ .

    The difference in price is usually $2 at most. I just go with Class 10 almost exclusively for that reason.
