"Sun engineers wondered if the 64-bit capabilities of current file systems 
will continue to suffice over the next 10 to 20 years. Their answer was 
no. If Moore's Law holds, in 10 to 15 years people will need a 65th bit. 
As a 128-bit system, ZFS is designed to support more storage, more file 
systems, more snapshots, more directory entries, and more files than can 
possibly be created in the foreseeable future."

Call me crazy, but does anyone else see this as hooey?  2^64 512B
sectors is 8192 zettabytes (zetta, exa, peta, tera, ...).

I'm also wondering what perversion of moore's law is applicable to
storage consumption.

Crappy marketing articles.
