Usually, we poo-poo any new memory card format what with the plethora of options available today. But when a new itty bitty card is announced with a ridiculous 2TB (2 terabyte!) maximum capacity (theoretical), well, we're willing to make the jump to a new format. SDXC (SD eXtended Capacity) relies upon Microsoft's exFAT file system and stores more than 4,000 RAW images, 100 HD movies, or 60 hours of HD recording with a transfer rate of up to 300MBps. The first batch of retail cards will hit before March with read/write speeds up to 104MBps in unknown capacities, though certainly less than 2TB on day one.
