SDXC
SD eXtended Capacity (SDXC) was introduced in SD specification version 3.01, released in January 2009. It expands the maximum capacity to 2 TB compared to the 32 GB limit of SDHC. SDXC cards are formatted with the exFAT file system, which is required by the SDXC standard. While Windows Vista SP1 and later and Mac OS X 10.6.5 and later support exFAT natively, support in BSD and Linux distributions was limited until Microsoft released the exFAT specification and Linux kernel 5.4 included an open-source driver.
