If your computer use involves accessing lots of files, I would suggest you mount your HDD with "noatime" option. You will see significant improvement because not every file-read will be written to filesystem.

So, in your /etc/fstab add this:

UUID=24d75db7-ceca-40f7-ac21-979870a15ad6 / ext4 noatime,errors=remount-ro 0 1

Hope this helps any.

hdparm is a command line utility for the Linux operating systems to set and view SATA and IDE hard disk hardware parameters. It can set parameters such as drive caches, sleep mode, power management, acoustic management, and DMA settings.

Changing hardware parameters from suboptimal conservative defaults to their optimal settings can improve performance greatly. For example, turning on DMA can in some instances double or triple data throughput.

Usage:

sudo su                   # Login as root

hdparm -tT /dev/sda       # Perform device read timings and cache read timings

hdparm /dev/sda           # To check the current settings of /dev/sda

hdparm -i /dev/sda        # Display drive identification.
