A '''yottabyte''' (derived from the [[SI prefix]] ''[[yotta]]''-) is a unit of [[information]] or [[computer storage]] equal to one [[septillion]] (one [[long and short scales|long scale]] [[quadrillion]] or 10<sup>24</sup>) [[bytes]]. It is commonly abbreviated '''YB'''. As of 2009, no computer has yet achieved one yottabyte of storage. In fact, the combined space of all the computer hard drives in the world does not amount to even one [[zettabyte]]. According to one study, all the world's computers stored approximately 160 [[exabytes]] in 2006.<ref>[http://www.emc.com/about/destination/digital_universe/pdf/Expanding_Digital_Universe_IDC_WhitePaper_022507.pdf Expanding Digital Universe IDC White Paper (pdf)] </ref> |

When used with byte multiples, the SI prefix may indicate a power of either 1,000 or 1,024, so the exact number may be either: |
|||
* 1 septillion, or 1,000,000,000,000,000,000,000,000 bytes — 1000<sup>8</sup>, or 10<sup>24</sup>, or |
|||
* 1,208,925,819,614,629,174,706,176 bytes — 1024<sup>8</sup>, or 2<sup>80</sup>. |

The term "[[yobibyte]]", using a [[binary prefix]], has been proposed as an unambiguous reference to the latter value. |
|||
One study has predicted that in 2010 the volume of online data accessible either on the Internet or on corporate networks is expected to reach a yottabyte.<ref>{{cite news | title=IBM Unveils Storage Capacity on Demand for Growing e-businesses | publisher=Business Wire | date=2001-10-27}} "In ten years, the volume of online data accessible either on the Internet or on corporate networks is expected to approach a yottabyte, or 1 trillion terabytes."</ref> The study refers to a yottabyte as 1 trillion terabytes. |
