hi, there are a lot of tweaks out there for ssd's and Linux! i have an 8 core amd with 32gbs of ram running Ubuntu 13.04. my 128gb Adata ssd has just one partiton (/) formatted using Ext4. here is how mine is set up:
all of my data is stored on 1tb and 2tb hard drives (i have made links in /Downloads, /Documents, /Videos, /Pictures and /Music which point to the data stored on those drives). i have edited fstab to mount the hard drives at boot.
i use no swap and have set swappiness to "0" ...see HERE
you can set trim to run in a variety of ways....see HERE (i use the cron job method). you can also execute trim manually with this command:
sudo fstrim -v /
i have also added the following lines to the bottom of my /etc/fstab file to lesson some writes to the ssd by creating a virtual ram drive for temp and some log files:
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0tmpfs /var/spool tmpfs defaults,noatime,mode=1777 0 0tmpfs /var/log tmpfs defaults,noatime 0 0
have fun tweaking!!
