Although technically SDHC card also supports 2 TB, the association in September to limit of 32 GB for them. Anyway, such capabilities require high transfer rates make them far more comfortable to use. SDXC the work to 104 MB / s and can reach in the future to 300 MB / s.

Compared with 6 MB / s offered by SDHC is not bad. Another difference between SDHC and SDXC is the first using the FAT-32 format, while the ExFAT to work with new disc format defined by Microsoft.

At the moment we are not, as the final specification will be launched this year and next will be in the CES will see when the first models.
