Question: What would you do with a 2TB SD card, a card of such voluminous capacity that you can hear cathedral-like echoes clanging around any MP3 file stored upon it?

To help you decide, here are some numbers: 100 HD movies, 480 hours of HD video recording, 136,000 "fine mode" photos, and enough MP3 files to last the rest of your life (this last is according to my poor math).

So, what would you do? the answer is, of course, lose it. And if it was the even smaller MicroSD card pictured, you'd lose it even quicker. Imagine dropping your entire photo collection down the drain when swapping out cards from the camera. Shiver.

Of course, you can't buy a 2TB card right now. Instead, SDXC is the new spec from the SD Association which allows a theoretical maximum of 2TB, meaning the way has been opened for manufacturers to offer bigger and bigger memory cards for cameras. It is also quick, with a current maximum transfer speed of 104 MB per second, rising to 300 MB per second when the kinks are worked out. Compare that to the 200x speed SD card which gives a comparatively pathetic 30 MB per second.

So, relax. By the time 2TB is actually affordable, you're camera will be recording 100 megapixel HDR images every time you click the shutter, so you'll probably only fit 100 photos on a card anyway.
