Topic: SD Card Compatibility

Important Note! While it is possible to use SD standard or SDHC standard based cards, we cannot guarantee that products other than a licensed SD card will work.

Information:
The Nintendo 3DS is compatible with SD cards up to 2GB in size, and SDHC cards of 4GB and larger.

MiniSD and MicroSD cards are compatible with the use of an SD Card Adapter.

There you have it. Nintendo doesn't recommend trying SD cards above 2GB in your systems. It looks like everyone who wishes to use larger cards should only consider SDHC cards.

i never knew that... im using a PNY optima SDHC 8GB! lots of extra room for all the new NES and GBA games that are coming soon:)

Quoting Wikipedia here:

The SDSC (standard-capacity) card family, commonly known as SD, has an official maximum capacity of 2 GB, though some are available up to 4 GB.

The SDHC (high-capacity) card family have a capacity of 4 GB to 32 GB.

Basically, most SD cards bigger than 2GB are in fact SDHC cards, so you should be fine

I just bought a 32GB SDHC card at Wal-Mart for $62. I now have 240,955 open blocks.

That's a helluva lot. I think Toshiba is making a 64GB card. Would love to have that. Always liked these SD cards because the memory sticks are too expensive if you buy it from Sony (PSP Official), as I got a 4GB Memory Stick for $20 at walmart and $7 at Target on clearance- while the official PSP Sony cards are nearly $40.

I hear you. I'm wondering what the Vita will use. Probably a Sony mem stick. One really underrated bonus to Nintendo's products is they're not trying to screw you on the extras like Sony does with it's PSP.

I was looking for this information!
The only thing i want to now is,
how to get all your files from the old (2GB SD) to the new (4-32 SDHC) i suppose to use a card reader and cutt off all your files???

Just copy the files too your PC/Mac and then Copy them to the new SD card!

Windows 7 allows you to quite literally select just the drive letter, & click "copy", then "paste" the copy into a location. I make back-up copies of my Wii, & 3DS data, so when my cards finally go faulty, or even the consoles themselves, I have spare data back-ups.

My 4 GB works just fine.

^What brand?

& I'm glad I checked this thread. I was wondering about this, & gonna do online research here on the forums, & @ other sites. Now I know. Most of my higher-than-2gbs are SDHC variety.

wow! you could have got one for $35 or a 64gb for $5 more dollars on Amazon.....
