SDXC Card read/write speeds up to 104MB/s> - 03-06-2009, 06:58 PM

This could be VERY interesting for the Netbook market.

Wiki entry about SDXC is fairly weak but I agree w/Holmes that the Mini's reader won't be able to take advantage of larger capacity/speeds of SDXC but may still be able to default to backwards compatibility of slower SDHC...

Sorry to resurrect an old thread, but I thought I'd mention that when I was at CES the guy at the SDXC booth told me that physically the SDXC cards were identical to the SDHC cards. He told me that an SDHC reader might not be able to reach the highest speeds of the SDXC format, but the higher capacities should work fine. Wikipedia at least seems to agree - "SDHC cards also have a maximum capacity of 2 TB based on the card data structures, but this is arbitrarily limited to 32 GB by the SD 2.0 document." (http://en.wikipedia.org/wiki/SDXC#SDXC)
The sticking point for "non-compatibility" is the ex-FAT filesystem with which they come formatted by default. Cameras and other devices designed for SDHC (and consequently FAT32) won't understand the new ex-FAT filesystem and therefore won't be able to talk to the cards. A Dell Mini running a newer version of Windows, however, should be able to understand ex-FAT and therefore might easily be able to use the card. Besides that fact, a reformat of the card would solve those problems, although as I understand it ex-FAT was chosen because FAT32 gets really inefficient (slow) at higher drive sizes than 32GB.
Most likely it will be just like those 4GB SD (not SDHC) cards that didn't obey the spec or the some of the current SDHC cards that are worlds beyond the highest "Class 6" rating speedwise. It may not be "standard" but it works fine. We'll see when they come out, I guess.
