I have an rpi2 which I've been running for almost three years now, and
which stays up 24/7. I run fstrim once a week from a cron job, and the
sd card is still doing fine as far as I can tell. While this doesn't
minimize write cycles, it does reduce wear on the card by distributing
writes to different sectors. The other suggestions in this thread are
also good ones.
