Set of all 40-GByte hard drives

A true 40-Gbyte hard drive contains 40 * 1024 * 1024 * 1024 bytes. At 8 bits per byte, this results in 343,597,383,680 binary bits.

Theoretically, the number of arrangements of these bits is 2 ^ 343,597,383,680. This is an insanely large number. In decimal notation, this number would be comprised of 103,433,118,919 digits.

Most of the hard drives would contain nonsense information. However, among the set of all such 40-Gbyte hard drives, you would find hard drives with the following contents. (Of course, each and every item listed below merits the following condition: Assuming that it would fit on a 40 Gbyte hard drive.)

Where would this set of hard drives be stored?  Not anywhere on Earth.  This set would occupy volume on the order of 10 ^ 103433118906 cubic Km.  That is much larger that the volume of the Milky Way galaxy (to say the least).
