Nope, it was Unity alright. The first LTS one—I think—so lacks a bunch of animations of the later releases. And even if that laptop is from 2009, it's CPU (Core2 Duo P9700) still scores roughly 30% of the today's top CPU single thread scores (those crazy AMD Ryzen 9s and such).
At first read it sounded like cold temps below 40C were problematic, but then the author recommends keeping the SSDs at temps below 40C. So then, if you leave the SSD powered off in an environment above 40C (104F), what then?
It's clearly untested, but the implication seems to be that data would survive for less than three months even.
(And funnily, Ubuntu 14.04 felt so fast coming from Ubuntu 20.04: terminal does not have any unnecessary animations, nor does Unity, and the experience is so much fresher, though I've got 920MB of updates that are installing right now and stressing the SSD)
So, perhaps the above warning only applies to more recent SSD technologies (MLC, TLC, QLC, GazillionLC and so forth :), or maybe IBM SSDs are messed up somehow.
