xlotlu (1395639) writes "The SD Association announced the Secure Digital eXtended Capacity (SDXC) memory card specification, supposed to provide up to 2TB of storage, and read/write speeds of 104 MB/s.
SDXC uses Microsoft's proprietary exFAT file system, which is available for licensing under NDA. There are currently no specific patents on exFAT, but its legal status is uncertain since it's based on FAT. The FAT patents have been previously upheld in court.
The Association is already looking forward to the next version of the specification, that will allow for speeds of up to 300MB/s"
