Optimization on SSD
1. Buy more than enough RAM
2. Use the default partition layout
3. Avoid using swap

echo -e "vm.swappiness=0" | sudo tee -a /etc/sysctl.conf

4. Disable access time logging

sudo nano /etc/fstab

   Now change “errors=remount-ro” to “noatime,errors=remount-ro”. Save the file and reboot.
5. Enable TRIM

echo -e "#\x21/bin/sh\\nfstrim -v /" | sudo tee /etc/cron.daily/trim

sudo chmod +x /etc/cron.daily/trim

monitor the expected life-time (This may not wok on VM)
1. install smartmontools

sudo apt-get install smartmontools

2.

sudo smartctl -data -A /dev/sda
