SSD's have no moving parts which makes them faster and superior to HDD's, providing more bandwith , performance and response time . They stay cooler , use less power , are lighter more reliable and completely silent . If you have a low end system an SSD upgrade would speed things up significantly (RAM upgrade would be recommended as well in order to keep the system from using swap , which will wear down the SSD) .
These settings have been tested on the a system with the following specs :
- AMD Quad Core APU-A6
- 8 GB RAM
- AMD Radeon HD 6520G
- Kingston SSD NOW 30GB
- Kingston SV300 120GB
We are going to begin this tutorial by checking the the Health of the SSD. Search for "Disks" in Unity Dash and launch it .
Editing and making rc.local executable :
sudo gedit /etc/rc.localBefore starting this process it’s a good idea to backup the fstab file:
sudo cp /etc/fstab /etc/fstab.bak
gksudo gedit /etc/fstab
Add the following
"discard" - "Enables TRIM to help manage disk performance over the long-term."
"noatime" - "Disables the updating of access time for both files and directories so that reading a file does not update their access time."
"nodiratime" - "Disables updating of access time when opening directories so that the access time is not modified when enumerating directories. This routine also checks that the object is a directory, which slows down the routine."
