MoonDisk

If Moon would be a big harddrive, made by current 3,5" 1TB harddrives, how much data it will hold? And do we need ever need build data-moon?


Given data:

Moon volume:  2.197×10^19 m^3 (cubic meters) source: http://www.wolframalpha.com/input/?i=volume+of+moon

Harddisk volume: 100 cm^3 = 1 * 10^-4 m^3  source http://en.wikipedia.org/wiki/Hard_disk_drive
moon_volume = 2.197*10e19 disk_capacity = 1.0*10e12 disk_volume = 1.0 * 10e-4 #moon volumen/how much 1m^3 will hold n_m3 = 1/disk_volume print "How many disk we can put into 1m^e:", n_m3 print "Moondisk capacity: {0}TB:".format(moon_capacity) 
        
How many disk we can put into 1m^e: 1000.00000000000
Moondisk capacity: 2.19700000000000e23TB:
How many disk we can put into 1m^e: 1000.00000000000
Moondisk capacity: 2.19700000000000e23TB:

It makes : ~~ 2.4×10^32 × estimated data content of the deep web (~~ 91000 TB ) and if we add 1TB new data per second then it will take: 

5.1×10^18 × universe age ( 1 universe age )
 to fill MoonDisk, too enourmous. 

Okay, lets go back to reality. How much room will take if gather all those diskdrivers, which are currently holding data content of the deep web?
91000/n_m3 
        
91.0000000000000
91.0000000000000

It just makes 

~ 1.3 × volume of a 1A-series freight container, or think cube with 4.498 meters edges.
