I have a 1GB SD Card for my Wii. Its full now so I want to upgrade to a much larger one.

I saw this one on play.com which seems a decent price

But it states:

PNY SD HC Secure Digital cards bring high capacity support for the next generation of digital products starting at 4GB thanks to the new SD 2.0 specfication. Fast (class 4 speed) reliable , SDMI (Secure Digital Music Initiative) and the content can be protected by CPRM based security. SDHC cards are not backward compatible with the previous SD devices and users should check the manuals of their digital devices for compatibility.

Is the Wii able to use these cards or not?

Im pretty sure they can.

I have an 8GB SDHC card, made by sandisk, in my Wii and it works like a dream. so I'd say you should be fine! The only thing that would concern me is that PNY is a cheaper make of card (hence the price) I was using a 2GB PNY micro sd with it's adapter on my DSi and it wouldn't work half the time.

SDHC cards don't work with Rock Band 2 or Guitar Hero World Tour, but I think they work with everything else.

Fine. You convinced me to get a Sandisk 8GB card as well. That should set me up for everything I will ever download. It was only a little more expensive than the PNY card but I'd consider it a waste of money if it only worked half the time like you said yours did.

I have an SDHC card that I use for my DSi, and every now and then I stick it in the wii to look at pictures, and it works fine.

The update that provided the SD menu also provided SDHC support; Wiis with prior firmware revisions cannot use SDHC cards and are therefore limited to 2GB (I think that's the old SD cap), which is also going to be an issue with older games that use older IOCs (as noted by LinktotheFuture).

So, if you have old games that make use of SD storage you'll probably end up doing some card swapping, but otherwise it's not a problem. With regard to make SanDisk is definitely one to trust (I think they actually invented the technology) and are reasonably priced since I believe they make more of the cards than anyone else in the world (though Apple seems to buy most of them for its iPod/iPhones/computers). I would also trust cards from memory-maker Kingston and veteran blank media outfit Verbatim. Lexar and Fujifilm are also good ones, but I'd only go that route for performance applications like video/photography with their high-speed pro lines.

I have a PNY card, and it works perfectly for me. I never posted in this thread before because I didn't realize what you were talking about. I have used it now for several months with no problems, and I have 24 VC/WW games saved to the card. All I use it for is VC/WW games, and I keep it in the Wii at all times, so I don't know its compatibility as far as anything else goes. If that's all you're using it for, then I recommend it, because it's never given me trouble.

I have an 8 GB in my DSi and a 16 GB in my wii. If you download a lot of games, you should be fine with 8 for your wii, but I have 54 games and 203 extra songs on GH5. Unless you are that kind of insane, I don't think you will ever need more than 8

@grenworthshero: PNY is a pretty reputable maker of PC memory, so I concur, they're probably a safe bet.
