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 10) bytes (one quadrillion gigabytes). The unit symbol for the yottabyte is YB.
As of 2012, no storage system or network has achieved even one thousandth of a yottabyte (a zettabyte) of information. The combined space of all computer hard drives in the world was estimated at approximately 160 exabytes in 2006, and as of 2009, the Internet was estimated to contain close to 500 exabytes.
Assuming a weight of 0.25 gram for a microSD card, a yottabyte's worth of data storage on the current 64 GB microSD cards would weigh just under 4 million tons, or about two thirds the weight of the Great Pyramid of Giza.
When used with byte multiples, the SI prefix indicates a power of 1000:
- 1000000000000000000000000bytes = 1000 or 10 bytes
The term "yobibyte" (YiB), using a binary prefix, is used for the corresponding power of 1024.
