The Entire Text of Wikipedia Is Only About 22 Gigabytes
All of English Wikipedia's article text, compressed, fits in roughly 22 gigabytes — small enough to fit on a basic USB drive. The full database with edit histories and metadata is much larger, but the sum of all human knowledge on Wikipedia is surprisingly compact.
