If you want to reinstall you can safely delete / and then add your 2nd disk. If your motherboard fries itself you can extract your personal disk and stick it into another system. If your boot disk breaks you can replace it and install an Ubuntu adding your personal disk.

Your OS does like speed (the personal cache files in /home/$USER also benefit from the SSDs speed) That disk needs to be durable as a HDD is (compared to an SSD). Your hdd is slow but your personal files do not need a quick disk. It takes me 19 minutes to reinstall including post install (apache and mysql for instance as I host websites from my notebook).ġ hdd for personal files including my websites and databases. Holding your system including /home with no personal files. But even then I would use the harddisk for the system and use a (quick) USB for personal files.ġ ssd for speedy boot. Only if you do not have 2 disks 2 partitions.

ALWAYS use faqs closed to the LTS you are at.

Faqs from before each need to be read with extreme caution or simply ignored. 2 examples: Ubuntu before systemd (so versions that used upstart), before wayland (as in systems before Unity). Anything before an LTS that breaks with previous versions needs to be ignored. A couple of things about the links you posted before I answer the 2 bullet points.ĪNY instructions from before the last LTS should always be read with caution.
