ext3fs journal.

If you do something like mount / -o remount,noatime,commit=3D600, the disk
should spin up only once every 10 minutes (assuming no programs need to
read a file that is not in cache in the meantime).

Debian/Ubuntu comes with laptop-mode that does this and a few other
things automatically -- but only when you are on battery power.

One could envision a different approach to persistence (hands wave and
magical stardust appears overhead to percussive indian string music)
where objects in the database were proxied rather than deriving from a
common base class.
