SanDisk Revealed a Monster 1-Terabyte SD Memory Card

SanDisk just effectively doubled the capacity of SD-based memorydevices, as they announced a one-terabyte prototype that will eventually head to stores.

It's a SanDisk Extreme Pro SDXC card, for anyone curious about which of SanDisk's many sub-brands this one fits into.

A terabyte is 1,000 gigabytes. That means if you're carrying around a 16GB iPhone right now, a memory card could hold that capacity 50 times over. When IBM's Watson debuted in 2011, it had about 16 TB of RAM and was the size of several refrigerators.

The card comes just two years after SanDisk achieved 512 GB capacity on a card.

There's no word on an exact release date, but when it comes out, uses for it will include totally optimized video recording, and pocketing a backup Skynet.
