It is, this infographic is wrong. Or I guess technically some other standard could define it like the infographic, but the Filesystem Hierarchy Standard defines it as a secondary hierarchy specifically for user data.

I don’t think that’s a fair assessment. Comparing to a traditional loop, it has marginally better thermals, one less set of tubing (i.e. places for leaks to spring up), and a smaller form factor. Wether or not those are “worth the money” is completely subjective. As someone interested in custom SSF builds I thought it was interesting.
