Sure, but you would also have to bring along a phone/tablet to show it off, or laptop/adapter.

Then how would you prove it had that much data? You can fake a sd card right now to show it has a huge amount of data on it.

I can hold up a piece of dust and claim it can hold 20tb, but no one will believe me.

That piece of dust might well hold 20Tb of dead genetic material from whatever created it... consider that a single human cell contains 3.2Gb of data in its DNA.

DNA is actually closer to 750MB (2.9 billion base pairs, 2 bits to one DNA sequence, so one byte to four sequences). Of course, a cell has other things going on in it (mitochondrial DNA, etc, so overall you're probably still right!

Mitochondrial DNA is only 17k base pairs. More important is the two main DNA copies per cell. But if you really want impressive numbers look at certain species of amphibians and plants that reach the 100 billion base pair range.
