I have a MUCH smaller /home than Dale and on a new box I was thinking of 
having it on a HDD, along with all things portage related.  I typically resync 
3 -4 times a week but I am not sure how much erase/write cycles this 
represents.  Also, /home is written all the time with mail and various 
application profile folders, browser cache and what have you.  That's why I 
was thinking that /usr/portage, /var/tmp/portage, /var/log, /home and /swap 
were candidates for HDD.

I guess the rest under / does not change that often and a weekly or even 
monthly back up would be all that is necessary to facilitate recovery when the 
SSD dies on me.

Am I being too cautious with current technology SSDs?

BTW, unless anyone advises differently, I was thinking of buying a SanDisk 
Extreme II, SATA III, 2.5" 240GB SSD.  I read that its SLC cache improves 
speed and reliability, but I don't know if true.
