Indeed I use such high compression to prolong SSD lifetime.
This is probably misguided and useless at best, at worst you're causing additional writes because compressed data is generally hard to modify in place without rewriting substantial portions. Concerns about SSD life are generally overblown unless you've got really unusual usage patterns (in which case compressing things is unlikely to make a difference).
For reference, my main desktop which tracks debian unstable and gets pretty much constant updates, does package builds, etc., has after several years used...2% of its primary SSDs write capacity. Most modern SSDs will never be used anywhere close to their limits before being discarded as functionally obsolete. Just don't worry about it and focus on other things.
