Applicable excerpts from the article: SSD: how to optimize your Solid State Drive for Linux Mint 18.x by ??? on Easy Linux tips project. This is an excellent guide.
Avoid quick wear: reduce write actions
Seven percent with a maximum of 10 GB of the drive should be left unpartitioned or unallocated as this seems to have a proven relation to SSD drive longevity. I used the quick install, then went back in with parted and resized.
The best file system (formatting) for an SSD, is the usual default EXT4.
With "noatime" in /etc/fstab, you disable the write action "access time stamp", that the operating system puts on a file whenever it's being read by the operating system. For an SSD "noatime" is much better.
sudo vi /etc/fstab
Now add the word noatime to the line for your root partition and your other Linux partitions, just before errors=remount-ro. Note: don't add it to the line for the swap partition!
/dev/mapper/mint--vg-root / ext4 noatime,errors=remount-ro 0 1
Limit swap wear
Check your current swappiness setting. Type in the terminal (use copy/paste):
cat /proc/sys/vm/swappiness
The result will probably be 60. - way to high for SSD and too high for a typical desktop workstation.
b. Now type in the terminal (use copy/paste):
sudo vi /etc/sysctl.conf
Add the following line at the end
vm.swappiness=1
