Back in December 2010 PQI announced that they were releasing an all-new SDXC Class 10 memory card that was 64GB in capacity! The PQI 64GB card breaks SDHC's former high capacity limit of 32GB by doubling capacity up to 64GB and upgrading the Class 10 SD 2.0 interface to high speed SD 3.0 specifications. The new SD Association's SD eXtended Capacity (SDXC) specifications have increased the capacity from 32GB up to 2TB. These new SDXC cards use an exFAT file system and it can obviously handle large volumes of data!  It also means that these 64GB cards are only the start of much larger capacities that will be released in the months and years to come.
