You get what you pay for. Cheap cards are slow no matter what "class" they claim to be. I have three 16GB cards (one Transcend and two Adata) that all claim to be class 6, but none of them read or write more than 4.5MB/s.
I thought the whole thing with the different classes was about the minimum speed the manufacturers promised the card would offer. Take a look at this SanDisk card for example:
Shown as a Class 2 card (by the looks of the label) but offers 15MB/sec Read/Write speeds.
I'm hoping we will see 64GB soon, 128GB in my Pandora makes me laugh
I think that someone will have to work around the specs to pull this off, kind of like they did with the standard SD format that topped out at 2gb. I know Transend put out a 4gb regular SD card. Someday we'll get there. The crazy thing will be if SDXC is doable through a driver update. We could end up having 4tb in our Pandora's in a few years.
Isn't SDHC good for 2TB?
There is a chance, and bear in mind I'm using guesswork here, that SD cards above 32GB will drop the 'HC' suffix and use the 'XC' suffix instead. After all, why did the original 'SD' label get dropped in favour of 'SDHC'? Increased media size + increased transfer speeds (as far as I can work out). What I'm trying to say is, don't be surprised if SDHC>32GB == SDXC, especially as the formats are controlled by the same group (http://www.sdcard.org/home).
