Wikipedia's active english data is only 24gb compressed. https://dumps.wikimedia.org/enwiki/20250201/

They store revisions in compressed storage mostly read only for archival. https://wikitech.wikimedia.org/wiki/MariaDB#External_storage

They have the layout and backup plans of their servers available.

They've got an efficient layout, and they use caching, and it is by nature very read intensive.

Archival read only servers don't have to worry about any of the maintenance mentioned. Use chatgpt or something to play your devil's advocate, because what you're saying is magical and non existent is quite common.
