To me, it depends on your application.  What I'm doing (and got me
digging here) is usb stick rootfs on a desktop turned NAS.

For the longest time I've been using logwatch to see if there's
anything I care about going on and short of an easily reproducible
system crasher, I don't care if I have logs for forever.  So I shoved
/var/log onto tmpfs, made logrotate compress and not keep things for
too long (and rc.local mkdir /var/log/{apt,samba}).  I also took a
look at what I do have running and made stuff that's writing/deleting
cache/log files I don't care about use /tmp, which is also a tmpfs.

That's not to say you can't keep /var/log and so on on the SSD and not
have it still have a rather reasonable life span.  But it does make
you question what you really care about.  Further, if you do really
care about logs, a coworker of mine setup something similar to what I
have except it plays fancy games to move the logging over to the RAID
once it's up.
