If I use a LiveUSB, non persistent mode, with the -toram command added to the boot options, will the USB's lifespan be reduced significantly? As far as I understand, LiveUSB runs entirely off the RAM, so the USB does not suffer from excessive write cycles, right?
The non-persistent LiveUSB does run entirely off RAM with the
toram boot option. It doesn't use read/write cycles of the LiveUSB.
toram boot option, I just tested to confirm. I pull the USB out during a session. None of the items would load after then, including the Ubuntu Dash search. Also, when I exited out of Firefox it crashed.
Also, the shutdown failed to complete successfully.
toram option all all test performs as normal with the LiveUSB removed after the desktop is loaded.
Details for adding the
toram option can be found at:
Can I boot a Live USB fully to RAM, allowing me to remove the disk?.
