The thing is, the linked article is a grab bag of outdated (mount filesystems with noatime [0]) or just plain wrong (btrfs is bad for SSDs) factoids and bits of advice. It's clear that the author hasn't gone to the trouble to fact or efficacy check most of his assertions. We need fewer top-ten lists of cargo-cult suggestions to extend the life of your PC, not more. :)
What's more, you're going to pains -however small- to extend the life of something that will easily last for far more than five years. Five years is a long time in the SSD market. My ~five year old 100GB SSD is still going strong. It cost ~$400 when I purchased it. Today I can spend ~$400 and get a 1TB drive that's substantially faster than and at least as reliable as this one.
There's something to be said for frugality. I know: I've been using the same laptop for the past eight years. There's also something to be said about not worrying about wear when using highly durable tools that are designed to last for a decade or more. [1]
[0] relatime has been available since ~2007 and was made a part of the defaults mount option since ~2009.
[1] After all, if a tool lasts for ten years, you'll only ever buy ten of them in your lifetime.
The page may look like there are many steps involved, but actually many do not apply to recent distributions. It's more or less a 4-5 steps for a recent distro. hardly what I would call "a lot of fiddly work".
