I just want to take a quick moment to disagree with your recommendation to put swap and/or /var on a traditional spinning disk in order to limit writes to your SSD. Yes, doing so may ultimately increase the expected lifetime of the drive, but you're missing out on the greatest benefits of the SSD by doing so. SSDs are extremely fast for random access patterns, but for sequential operations (such as reading or writing large files) they aren't significantly faster than spinning disks. The parts of your system that perform the most random access operations are likely to be swap and /var. Speeding up swap is quite possibly the single best application for an SSD in a linux system.
