At a recent Microsoft-sponsored database conference, Paul Flessner, Microsoft Senior Vice President of Server Applications, discussed the growth of data capacity requirements in layman’s terms:
- 1 MB (one million characters or so) = two novels (about 500 pages);
- 1 GB (1,000 MB) = about 1900 novels;
- 1 TB (1,000 GB) = about 1.9 million books (requiring 15 miles of bookshelves and 50,000 trees);
- 10 TB = about the size of the Library of Congress (LOC), or 19M books;
- 1 PB (1,000 TB) = 100 LOC's; in dollars, more money than in all the world's banks;
- 12 EB (1,000 PB) = total of human knowledge through 1999 (about 1.2 million LOC's)
The next 12 EB were created by 2002; 7 EB was created in 2003 alone.
At this rate, I don’t think humans could possibly keep up with all the data created and recorded.
It’s also clear that we keep accumulating data and that with technology, there is no restriction on the amount of data we can keep.
Anyway, I was wondering, after we get beyond the next+next 12 EB my question is: Where and how the data is going to be used?
