There are several tweaks you'll want to apply to prolong the life of
your SSD:
* align the FS properly (this'll be the biggest PITA to figure out
whether it's done correctly, seek help from google). Latest firmware on
Intel SSDs claims to not need this, but I'd do it just in case.
* enable noatime,nodiratime in /etc/fstab -- reduces number of writes
* if you don't much care for the logs in /var/log, turn them off or
redirect to a ram drive -- reduces number of writes
* switch io scheduler to noop -- speeds up random reads

This is by no means a complete list, just stuff off the top of my head.
