Just wondering if anyone's seen any sign of a 32gb Microsd yet. I'm kinda chomping at the bit for one. Plus I need them to come out in order to lower the price on 16gb.

I think that the SDHC standard changes at 32Gb. I don't remember exactly what it changes to off the top of my head - but my understanding is that to support anything larger you would need a firmware upgrade.

I will look into it and update my comments when I find it.

SDHC supports up to 32GB cards with fat and SDXC will come next, is hardware compatible, but uses exFAT to get up to 2TB cards (one can wish ;-)

R-R, it's doubtful they'll go to 2tb. They claimed that for the previous two versions, but ended up simplifying the standard in the end, thus leading to the cutoffs we saw. We're predicting that SDXC will top out at 512gb for two reasons. 1) 512 will hit the physical limit for storage in this form factor, and 2) the standard will once again get simplified along the way, limiting its top end.

However, I'm thinking that 1) will be the big deciding factor, as you'd have to go to some crazy small processes (sub 22mm) in order to get that density of storage, or else move to the new carbon-nanotube storage, which really is the more likely of the two. That and quantum storage are really the only ways in which we'll break the 512gb barrier on SD flash memory. Then again, who's actually going to need a flash card bigger than that! Good lord, I'll be ages even using up 32 gb in my portable devices. The only reason I'd have for going higher is long term storage and/or backup of my storage arrays.

Which brings up another point. Flash hard drive raid arrays for long term, stable backups would actually be a very practical solution. Durability + long life = win!
