I'm sure /home gets its share of reads and writes and= was thinking the writes would cause a problem over time.

At some point I found this at ArchWiki page about SSDs[1], but I don't know how up to date or correct this is. "A 32GB SSD with a mediocre 10x write amplification factor, a standard 10000 write/erase cycle, and 10GB of data written per day, would get an 8 years life expectancy. It gets better with bigger SSDs and modern controllers with less write amplification." Now I have /var/tmp/portage on tmpfs and a swapfile on the SSD, but I think the drive will last for the next years so i don't have to worry much about it.
