A zettabyte is a unit of information equal to 1,024 exabytes or approximately 1,000,000,000,000,000,000,000 bytes.

Also known as ZB Definition 2 to the 70th power bytes, which is approximately 10 to the 21st power (1,000,000,000,000,000,000,000) bytes. A zettabyte is equal to 1,024 exabytes.

A unit of information or computer storage roughly equal to one sextillion bytes. It is commonly abbreviated ZB.

In non-technical terms, this is "big bytes"; in the American system, it is called sextillion. In more formal and definitive terms (just how big is this?), it is 2 to the 70th power bytes (2^70 = 1,180,591,620,717,411,303,424), which is approximately 10 to the 21st power (you knew that didn't you) bytes (1,000,000,000,000,000,000,000) [..]

A zettabyte is 2 to the 70th power, or 1,180,591,620,717,411,303,424 bytes. It can be estimated as 10 to the 21st power, or 1,000,000,000,000,000,000,000 bytes. A zettabyte is 1,024 exabytes and prece [..]

Unit of storage. Often abbreviated to ZB. 1 ZB = 2 to the seventieth power bytes = 1,180,591,620,717,411,303,424 bytes = 1024 exabytes . 1024 zettabytes = 1 yottabyte.

It is a unit of information or computer storage equal to one sextillion. A zettabyte is 2 to the 70th power, or 1,180,591,620,717,411,303,424 bytes. It is abbreviated by ZB.

Maybe some day this word will catch on. I think the editors were a bit ahead of their time in this case. The scale goes: kilo, mega, giga, tera, peta, exa, zetta. So, we're a few years off from this becoming a household term. 

1,024 exabytes, or 2^70 bytes. Abbreviated Z, ZB, or zB. See bit, byte.

2^70 = 1,180,591,620,717,411,303,424 bytes, which is 1024 exabytes.

A zettabyte is a unit of information equal to 1,024 exabytes or approximately 1,000,000,000,000,000,000,000 bytes.

A zettabyte (ZB) is a unit of digital information storage used to denote the size of data. It is equivalent to 1,024 exabytes or 1,000,000,000,000,000,000,000 bytes.
