I was trying to figure out how long I had been using Linux, so I stumbled across that review of the first Distro I really used, I used the Mate, XFCE, Debian versions until I started using Mainly the KDE one, which finally broke, after dist-upgrade about a month or two ago.
The author of the article stated XFCE needed "830+GB at the "normal" download payload".
For those keeping track, XFCE is a lightweight desktop that requires a Terabyte Drive to run
The hardest part of course is keeping track of all the discs, and making sure you install them in the right order.
This might explain why XFCE is behind in their developmental schedule, they are still downloading.
