I just got an email about a new SD card standard that was just announced at CES by the SD Association. I guess SDHC is old news already with its paltry 32GB max. I can already see my dreams of a 2 Terabyte BlackBerry… All they need to do is slap a micro tag in front of it.
SDXC stands for SD eXtended Capacity. I guess that is better than SDHC (High Capacity) Nothing much new other than the fact that the standard allows for super fast transfer speeds. It accelerates SD interface read/write speeds to 104 megabytes per second this year, with a road map to 300 megabytes per second in the future.
The SDXC specification uses Microsoft’s exFAT file system to support its large capacity and interoperability. I don’t know much about this new file system other than the fact that it was designed for increased compatibility with flash media, from portability of data to interoperability with multiple platforms and devices on removable media.
