Thinking maybe I could create a piece that took as much storage as the human brain, I did a bit of research:
According to this site, the brain holds 10^20 (100,000,000,000,000,000,000) bits of data. When worked out:
100,000,000,000,000,000,000 bits (8192 bits per kb)
or
12,207,031,250,000,000 kb (1024 kb per MB)
or
11,920,928,955,078.125 MB (1024 MB per GB)
or
11,641,532,182.7 GB (1024 GB to TB)
…means the brain holds 11,368,683.8 TB of data… way beyond anything available for purchase. Yikes!
Another nice breakdown of data storage history and relative sizes is at this Museum of American Heratige page.
