The yottabyte (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 (one quadrillion gigabytes). The unit symbol for the yottabyte is YB.

When used with byte multiples, the SI prefix indicates a power of 1000:

1000000000000000000000000bytes = 10008 or 1024 bytes

The term "yobibyte" (YiB), using a binary prefix, is used for the corresponding power of 1024.

To store a yottabyte would require a million city block size data-centers, as big as the states of Delaware and Rhode Island.[1]
