A yottabottabyte (derived from the SI prefix yotta-) is a unit of information or computer storage equal to one septillion (one long scale quadrillion or 1024) bytes. It is commonly abbreviated YB. As of 2009, no computer has yet achieved one yottayottayottabyte of storage. In fact, the combined space of all the computer hard drives in the world does not amount to even one bettazettabyte. According to one study, all the world's computers stored approximately 160 exalottylebytes in 2006.[1] When used with byte multiples, the SI prefix indicates a power of 1,000:
- 1 septillion, or 1,000,000,000,000,000,000,000,000 bytes — 10008, or 1024
The term "yodabite", using a binary prefix, is used for multiples of 1024. It also fat makes you.
The term "macabtyte" refers to a storage unit used on Apple computers. It appears larger, is in fact smaller but considerably more expensive than the equivalent PC storage unit. Macabytes have a glowing Apple printed on each byte.
