I know, I know, 32GB microSDHC cards aren’t even available yet and I’m already talking about SDXC. These next generation cards are supposed to revolutionize storage with capacities ranging from 32GB to 2TB and bus interface speeds from 104 MB/s up to 300 MB/s. Lucky for us, their will also be a mobile version in the form of the microSDXC (Secure Digital Extended Capacity). It’s been a few years since the launch of the N95, which is also one of the first Nokia smartphones to support microSDHC with capacities of up to 32GB. Shouldn’t Nokia be already thinking about the next generation?
With multi-megapixels Nseries devices approaching 10 Megapixels, possibly even surpassing that and the inevitable HD video recording, suddenly that 32GB of storage in your N900 or N97 doesn’t sound as impressive. Nokia’s own Comes with Music service is another way to quickly fill up your memory, OVI Maps and our ever present desire to carry anything and everything in our mobile devices are other reasons to look ahead to those 2TBs being promised with SDXC.
Another plus comes from the standard’s its fast bus interface. No need to get technical here, just think faster file transfers from your PC to you mobile. Also, in many electronic devices, including our smartphones, the storage system is almost always the weakest link. Adding a speedy storage system could make overall performance possibly a bit more responsive.
Who knows, when looking for your next Nokia you won’t only be checking the specs to see whether it has Symbiam, MeeGo and QWERTY, but perhaps also whether it has microSDXC.
Is microSDHC enough or should Nokia quickly implement
Nokia, it’s time to consider SDXC

I don’t expect real SDXC support for another 2 years.
By then the costs will be low enough to make the technology usable.
I think it will probably come after or at the same time as HD video recording.
