Depends on whether that storage will last for millenia (and still be readable with simple technology) or for a decade. I worry what percentage of valued storage (digitization of valued objects followed by their disposal) will remain in 50 years. I think of the Eloi libraries (whether Pal's disaster or those of H.G. or Simon Wells.) We can find only faint echos of most profound 'Ancient Greek' texts.
