Magnetic disk hard drives will always be king. They beat them
(opticals), even though they dropped to a mere one or two disks (disk
surfaces) (two "disks" per physical platter are possible). They used
to be several platters in days of old.
This is why the new perpendicular technology will likely be only on
1" and 2.5" form factors. Smaller is better, faster, less massive,
etc., etc. Bookshelf hard drives (caddies) are coming. It is very
similar to console game cartridges of the old days. Our now
standardized "DVD box" containers could be adapted to hold it when not
in use. One's shelf would be full of game titles, books,
encyclopedias, foreign language training, maps, standards references,
thesuarus(es), etc. Instead of installing an app, one will install a
drive (hot swap), and then run the app that is on the drive. Viola!
No more piracy. Every product author can have their very own file
system that cannot then be copied without a LOT of headache, and only
on a one by one basis. It is perfect. No more cheating on the
copyright owner! Also, the serialization of EACH game sold can be
different, unlike with pressed optical disks, making it even more
impossible to use by more than one person.
