Browsing through computer ads, I see a lot of home computer systems are equipped with a 1 Terabyte hard drive. If you’re like me, that really doesn’t mean much. I have no sense of how much space that is.

Here is a visual illustration. Glancing on my bookshelf, one of the thickest books I own is “War and Peace.” It is availabe as an electronic file on Project Gutenberg. The plain text is 3.1 MB (megabytes). There are 1024 megabytes in 1 gigabyte. So I can fit about 330 War and Peaces on a gigabyte. There are 1024 gigabytes in a terabyte.

So a 1 terabyte drive will hold 337,920 copies of War and Peace.

For a frame of reference, the Kindle store clains to have over 950,000 books most of which are not as big as War and Peace (plus Kindle files are smaller than plain text files). So if I bought every book in the Kindle store (assuming no pictures), I could fit them on three 1 terabyte drives.
