mount

• Filesystems

For a simple, safe performance-saving option, add noatime to not have the filesystem update access timestamps when a file is read.

/dev/sda1               /               ext4            noatime         0 1

Use discard as a mount option for SSD drives:

/dev/sda1               /               ext4            noatime,discard         0 1
