A googlebyte is the largest possible measurement of storage capacity. It is based on the number googol, which is a 10 followed by one hundred zeros. It represents several quintillion times the capacity of the largest current installations of around one petabyte (or one billion megabytes).
“To put this in perspective,” Larfey says, “if each byte of data stored in a googlebyte were the size of a grain of sand, then this server farm would be a thousand times the size of the Sahara Desert. If those grains of sand were laid end to end, they would stretch from the earth to the center of the Milky Way galaxy.”
