Noatime
Every time a file is accessed the kernel writes this information back to the disk, disabling it will make file operations faster and make your SSD last longer.
sudo nano /etc/fstab
Find the line that contains your system partition. For non encrypted systems (the most common) it will look like
UUID=7e5152ce-37d3-4b4e-b1a3-1b8d4bc3cd02 / ext4 defaults 0 1
OR
/dev/sda1 / ext4 defaults 0 1
For LUKS/encrypted systems it will look like
/dev/mapper/luks-608607c7-a1e5-423c-929f-6c18fea / ext4 defaults 0 1
ADD noatime after the defaults so it looks like
UUID=7e5152ce-37d3-4b4e-b1a3-1b8d4bc3cd02 / ext4 defaults,noatime 0 1
Remount the system to check it works
mount -o remount /
If there are no errors then you can safely restart, if there are errors then revert your change.
