Sort of...NT does disk caching just like everyone else.  This is just a
service that makes sharing state easier.  It's especially nice for web
application or stateless components where it's dog slow to go to the
database for every hit (unless you're using MySQL, of course ;-).  Its all
RAM based (which is nice).  You can talk SQL to it (which is convenient).
Its even almost ACID (except for the D, of course).

Its a replacement for another MS service (the Shared Property Manager) which
pretty much blew chunks.

Keeps you from having to write one up yourself.
