It's a lot...But bases are reasonably sized molecules, not to mention the sugar phosphate 'scaffolding'; it's not totally unreasonable to imagine you could build something which handled the same amount of data with fewer atoms; or trim some of the extra stuff away, start substituting other atoms, or use other base modifications (e.g. methylation, glycosylation, I think) to increase data density.

truei guess one of the denseist you could get is a lattic of e.g a metal with two atoms, with the atom at the lattice point dictating the 1 or zero.
use Li/Na, one mole~10gms, which would give Nabits (Na= avagadros number)=~10E22B/gm, which is about the same, which makes me suspect that wiki may be lieing

That's bits stored per gram, which might be true.Carbon and hydrogen atoms are lighter than sodium and lithium respectively....
