I'd advise against doing extra over-provisioning and making /swap on slow HDD. IMO it is a thing of the past, especially on a home\personal computer. Modern NAND technology and provisioning algorithms made SSDs quite resilient. It is more likely that a controller IC will fail than a NAND ICs will wear off themselves during mild daily usage.
I disagree. I was quite surprised that my 2x Crucial MX500 250GB 3D drives which I use in mdadm RAID1, saying that they are 12% used in 2 years of use. That's because I created one big partition for entire drive and used it that way. Most of it was free anyway. They are used as / in my server, mostly just idling, as all work is being done on HDD RAID (/home and /var is on HDDs too). Now, I trimmed down Ext4 partition and mdadm RAID surface underneath it, and left free space at the end of the drive. Slow creep of life used has stopped and I am on 12% on both drives for few months now. Nothing else has changed, and life use stopped. Maybe Crucial drives are just more honest than other drives who say 2% use after 5 years of operation? -- With kindest regards, Piotr. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org/ ⠈⠳⣄⠀⠀⠀⠀
