I read the changes, and it seems to me it was a stupid child. Not even someone malicious, but just a stupid love being edgy.
I would create an LVM and combine the two to get 3TB in one logical disk.
Let me suggest you to switch to Fedora, Arch or Opensuse. Debian Sid may have problems, and stable is simply too slow for how fast Nvidia is moving. My suggestion is to use Fedora or Arch, or Opensuse, with newer packages. Everything was super smooth on Fedora.
But the profiles are pretty poor and basic AFAIK.
Nothing will make your system magically more secure, but SELinux is of great help when properly set up (as is in the case of Fedora).
That's unrelated to this.
So does mine. I installed Fedora on an old, 4GB laptop connected to a monitor for her to watch Netflix and TV on her bed. We literally reused a laptop from 2013, an old 900p monitor and a VGA cable + a cheap, poor quality Amazon speaker I was not using at all. I'm really happy with how everything turned out.
I mean, it could be possible that the box of the mouse said something like kernel 2.6+. Considering that is older than 2011, OP's answer was absolutely spot on.
Such a shame. The best distro out there being hurt by these decisions...
He likes Ubuntu because he's familiar with it, plain and simple. He dislikes Arch because of the toxic trolls there, and dislikes Fedora for... undisclosed reasons...
It always did, though. Just unofficially.
And Steam is a show of success
