Also interesting to note:

------------------------------
"The decreasing cost of storing data and the increasing storage
capacities of ever smaller devices have made massive amounts of
information and multimedia available and easily accessible in every
corner of the world. To date, improvements in conventional technologies
-- such as magnetic hard disk drives, optical disks and semiconductor
memories -- have been able to keep pace with the incessant demand for
greater and faster storage.

However, there is strong evidence that these surface-storage
technologies are approaching fundamental limits that may be difficult to
overcome, as ever-smaller bits become less thermally stable and harder
to access. Exactly when this limit will be reached remains an
open question: some experts predict these barriers will be encountered
in three years, while others believe that conventional technologies can
continue to improve for at least five more years."
------------------------------

That was in early 2001. It hasn't beem three, nor five, but /fifteen/
years since then, and storage capacity per area still keeps increasing
in both magnetic hard drive and semiconductor memories. (Optical media
not so much, but this may be mainly due to a decline in demand.)

What hasn't kept up with the trend is data transfer performance. Main
RAM latency has been virtually stagnant for about a decade, and
bandwidth of any type of established storage medium has also been
increasing far slower than capacity.
