Hi I am thinking to get 2x64gb memory card . C100,c100mark2 seems to support both SDHC and SDXC . As far as I know SDHC (FAT32) and SDXC (exFAT) . fat32 can handle only 4gb clip , so every time when I record something longer it automatically makes smaller files . Is this happen the same in SDXC card ? Which one is better ?
