I don't see much issue with swap on SSD as long as it isn't used too much. My laptop only has SSD, my desktop also has a spinning-rust disk for scratch- heavy (many, many writes) activities. My swap is on SSD, it's not used often, I guess I would wear out that SSD sooner with the activities of my home-dir and akonadi. :) I don't see anything bad happening yet using smartctl and this machine is running a lot lately with, for my desktop, quite high uptimes. -- Joost
