OK I read that the Wii can support SD cards up to 2 GB then I read of an update that removed this limitation.

What is the actual maximum SD card size the Wii can support if I keep it updated with official updates from Nintendo? Also is there a limitation on the SD card type (SD, SDHC...)?

The "wii" doesn't deal with the SD card at all. the Software running on the Wii supports the SD card. Older games run older software. newer games newer software. – gcb May 3 '13 at 2:22

The other thing to bear in mind is that some (older) games won't recognise larger cards so you may end up having to buy several cards anyway.

We have a 8GB card that the kids store Wii channels on that works just fine, but Guitar Hero won't recognise it so we have to use a 2GB to store the GH downloadable content (extra songs etc.)

I didn't know this, good bit of information to have. – Doozer Blake Feb 28 '11 at 14:38
Rock Band 2 has the same issue. It cannot use anything bigger than 4GB. – au revoir Mar 1 '11 at 0:44
This explains things. :-) How many Guitar Hero songs is that? – Roger C S Wernersson Apr 18 '11 at 12:40
@Roger - I'll have to ask @Ronan – ChrisF Apr 18 '11 at 12:43
Has any on got info on the 256MB memory Card for the Wii? – user22692 Mar 29 '12 at 0:58

With Wii Menu 4.0 and above you can use up to 32gb SDHC cards. Full details can be found on Nintendo's customer support site.

You can use SD, SDHC and miniSD or microSD with adapters.

I think the important thing to note here is that the wii seems to prefer Fat and Fat32. Fat32 maxes out at 32gb, so anything larger than that is going to probably get stuck in NTFS or exFat and the Wii isn't going to know what to do with that. If you had something larger than 32gb, you could partition it, but most likely you'll only be able to read the first partition, which can only be a maximum of 32gb. So.. 32gb, that is basically the max.

Actually, the limit for fat32 is considerably larger than 32gb, but windows will not natively format fat32 to partitions larger than 32gb - but a specialized program like Ridgecrop's FAT 32 Formatter can do it quite handily (and they have a gui version). Most, if not all, devices that support SDHC will support larger capacity SDXC cards (64gb+) that have been re-formatted in this way. See also my answer here. – Trent Hawkins Oct 11 '13 at 3:20
