you and me and everyone else.

1 YB = 10008bytes = 1024bytes = 1000000000000000000000000bytes = 1000 zettabytes = 1 trillion terabytes

That means if your personal computer has a 240GB hard drive, you would need 4 trillion computers to equal the storage space of this data center. In 2010, it was estimated that storing a yottabyte on terabyte-size hard drives would require one million city block size data-centers, as big as the states of Delaware and Rhode Island.[1] If 128 GB microSDXC cards (the most compact data storage medium available to the public as of early 2014) were used instead, the total volume would be approximately 1250000 cubic meters, or the volume of half of the Great Pyramid of Giza.

That's kind of big.
