New Card format holds 2TB

The SD Association released the specification for a new format SD card known as SDXC which can hold up to 2TB of information. They will also support read/write speeds of up to 104MB/s – though assuming the cards can sustain that speed, it will still take 20,000 seconds to fill a card (about 5 1/2 hours). It is hoped that in future the speed will rise to 300MB/s.

The cards will use Microsofts exFAT file system and will hold 60 hours of HD video (about 100 High Definition movies).
