Recently, the SD Association announced the choice for exFAT, a standardized division that is supported by Windows VISTA and also works with Windows XP, CE and the future Windows 7 operating system. We have yet to see which hardware will be the first on the market supporting this new SDCX format. High Definition camcorders are very likely to be the first, while this type of equipment requires large storage capacities. In addition to expanding the amount of GBs to an impressive maximum of 2TB (Terabyte), speed is equally important. Where a maximum speed of 25MB/sec is reached, it will reach an astonishing 100 to 300MB/sec after the increase of bus speed by 50.

its an old story... but its tiny, stacking a few of them would result to a matchbox size terabyte storage.

makes me wonder why they couldn't design SSDs to be this tiny.

Freedom Kira:
Because a) that small size isn't really necessary (and actually there was an article last year about Samsung Sandisk creating a tiny SSD (called iSSD) intended for use with ultramobile devices); note that SSDs tend to be 2.5" because they fit in laptops that way, and b) that's a ridiculously expensive idea. A 32GB MicroSDHC card costs roughly $70 these days. As you increase the space into SDXC capacities, the cost increases exponentially. A good 40GB SSD costs about $100 now and prices are expected to drop significantly in 2012.

kitamesume:
^true, well the 2TB versions of the SDXC arent out yet either. but i think they`ll bring the prices down as well, seeing a 2TB @ 600$++ would just be rediculous, and as the article says, it should have a 300MB/s speed so speed wouldn't be an issue.

64GB SDXC is at 115$ right now on newegg.

AnimeJanai:
If you stack them up to fit in a "matchbox", don't you have to worry about heat?  If regular use didn't make enough heat, but cyclic use like in a memory thrashing program did that, then technically, use of the stacked SDXC "matchbox" would make an exploit possible.  A program could be made that accesses only the memory addresses of the chips located in the middle to generate heat to attempt burning up some memory.

kitamesume:
well it is possible to mount them on a flat heatsink, that should spread the heat. just like making a sandwich.
