Actually in the case of DNA computers they trend to be pretty self supporting they act as CPU,Memory and as a power source. They would need a lot less supporting devices than any other methods..
A single DNA string is fairly useless. It is effectively a memory storage & a list of instructions to run when the string is processed.
A DNA string requires an external reader to trigger the changes & do the work.

Think of DNA as software, and enzymes as hardware. Put them together in a test tube. The way in which these molecules undergo chemical reactions with each other allows simple operations to be performed as a byproduct of the reactions. The scientists tell the devices what to do by controlling the composition of the DNA software molecules. It's a completely different approach to pushing electrons around a dry circuit in a conventional computer.
A single 1 of these nanites isnt useless, and they are independant agents.
Also:
1 trillion exabytes is (10^12) * (10^18) = 10^30 bytes.
At ~6 million GB per cubic millimeter, it would take ~1.79 *10^14 millimetres to equal that.
Thats ~1.79 *10^5 cubic metres.
But keep in mind, that isnt a single memory core, but a shit load of nanites.
If you stripped out everything but memory storage you could probable drastically reduce the equired volumn.
His Divine Shadow, the real question is how big are those things and what size operation requires them.
