Until now I have used Raspberry Pi with micro SD card and while it works for some times I have had lot of corruptions. Not shutting Pi properly down plus unstable power wreak havoc on the SD card. And as you may have read from my previous tutorials I like to run servers on my Raspberry Pi so yeah SQL + logging = high read write are no way to treat small SD cards.
So for loads like that there should be more robust solution.
And for that here is small write up how to use USB thumb drive or USB hard drive as your Raspberry Pi-s root drive. You still need SD card for boot but as you learn from this tutorial it is much easier to replace the static boot drive then whole system, especially if you haven’t backed up your system 10 seconds prior to failure.
