I remember that I've given this second advice. Since then I've read in the German computer journal c't [1] that CFQ has a detection for SSDs since 2.6.28 and now is the best choice for these devices. > 3. disabled DRI to save 32MB RAM > 4. removed the swap partition from /etc/fstab > > Am I missing anything significant?

You can name it in every way you want it. For further tweaks: Do you use Firefox? I've read that it uses fsync() when writing to its sqlite backend. This is a really good thing because it reduces the risk of loosing data but you might (and can) disable this to increase performance and reduce wear. I don't have a link at hand but it shouldn't be to hard to find. [1]c't 11/2009 page 101
