Here’s one to make the kids weep into their 64GB iPod Touch devices. Panasonic has unveiled what will be the first commercially available SDXC cards, and they did so at CES. To the left is a 64GB card, priced at a measly US$599.95, and they also have a 48GB model for a mere US$449.95. They both have a class 10 rating and can push and pull 22MBs/second. Not too shabby, but better can be done. The SD 4.0 specification is supposed to top out at an astounding 2TB of capacity and up to 300MBs/second transfer speeds.

Now, I’m sure you can well imagine what this kind of storage could be used to improve. I’m thinking that 8 of the component units on a micro backplane could yield 512GBs of storage in, and I’ll be generous, the space of 12 SD cards. I think we’re going to be seeing some amazing things this year in mobile devices, mass storage, digital media, and who knows what else! I’m driven mad just by the thought of one of these 64GB cards.

ADDENDUM: You know, I just realized how much this sucks. Everything cool has a really compact, very functional, pretty sizable (for now) microSD card slot in it. This is going to be for all those camera wonks, isn’t it?
