An technical facility with an diameter of 1 centimeter could store 10 ^ 66 
bits. The maximal capability is limited by the entropy of the system, the 
whole visible universe has an entropy of 10 ^ 100 bits. The absolute border 
is the holographic border, a system increasing information storage over the 
holographic border will turn into a black hole.

This may be stuff for an fortune ;)
