Applicable modified 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.

This is an adapted and truncated version applicable to Mint Linux 18 and most probably Ubuntu, Kubuntu, Mint, and other Debian derivatives.

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
