The '''yottabyte''' is a multiple of the unit ] for ]. The ] '']'' indicates the eighth power of 1000 and means 10<sup>24</sup> in the ] (SI), and therefore one yottabyte is one ] (one ] quadrillion) bytes. The unit symbol for the yottabyte is '''YB'''. |

To store a yottabyte on terabyte sized hard drives would require a million city block size data-centers, as big as the states of Delaware and Rhode Island.<ref>{{cite web|title=The One Hundred Trillion Dollars Hard Drive|publisher=Gizmodo | url=http://gizmodo.com/5557676/how-much-money-would-a-yottabyte-hard-drive-cost | accessdate=7 March 2013}}</ref> If 64 GB ] cards (the most compact data storage medium available to public as of early 2013) were used instead, the total volume would be approximately {{gaps|2|500|000}} cubic meters, or the volume of the ]. |
