multiple of the unit byte, equivalent to 1,000 zettabytes

A yottabyte (YB) is a unit of measurement for computers of the future. One yottabyte holds 1000 zettabytes (ZB) or a trillion trillion (1,000,000,000,000,000,000,000,000) bytes. 1000 yottabytes make up 1 hellabyte.

A yottabyte is so large that it would take about a billion supercomputers to store this amount of data.
