I am surprised the article doesn't mention monitoring TBW (TerraBytesWritten). I found it a good indicator for how much data is actually written to the SSD. In my case, I decided to buy cheap consumer SSDs (from WD), because I calculated I have only about 50TBW per year on my VM-drive, a ZFS-Mirror. In reality, it is even less - so far 14TBW in 2022, with 16 VMs. See a blog post here for how I monitor the stats in InfluxDB [1]. WD says the drive has an average lifetime of about 300 to 400 TBW, so I can expect at least another 5 years.
