I gave up trying to do fancy write minimization strategies for SSD's a long time ago as they usually had a performance penalty and I am using SSD's for their considerable speedup - I currently have about 5 SSD's and in addition you can add laptop nvme, m2.nvme etc to the list as well. I run normally - that is swap and compiling caches etc on the SSD. Over that last few years I have had one SSD fail (and 3-4 spinning rust!) - the SSD failure was a random event (it was a "good" intel one) as it just died out of the blue. It was being used as a bcache cacheing drive at the time, and one of the 4 HDD's in the system failed around the same time so I suspect and external event rather than internal to the SSD. The OS drives with swap and compiling have not caused any problems - one early generation 60GB spent its first 18months as a ceph node (really hammers the drive) and its still the main OS drive on my desktop. My comment is that these days, SSD's are not a concern or warrant special treatment and that an SSD failure is likely to be sudden and catastrophic unlike a normal HDD which usually degrades and gives warning signs of impending doom :) BillK
