A zettabyte (derived from the SI prefix zetta-) is a unit of information or computer storage equal to one sextillion (one long scale trilliard) bytes. It is commonly abbreviated ZB. As of 2007, no computer has one zettabyte of storage. When used with byte multiples, the SI prefix may indicate a power of either 1000 or 1024, so the exact number may be either:
  • 1,000,000,000,000,000,000,000 bytes — 10007, or 1021.
  • 1,180,591,620,717,411,303,424 bytes — 10247, or 270.
The term "zebibyte", using a binary prefix, has been proposed as an unambiguous reference to the latter value.

The Z in Sun's ZFS file system originally stood for zettabyte. The IDC estimates that by 2010, there will be 988 exabytes, just under a zettabyte, in all computer storage world wide.[1] Reference: IDC whitepaper sponsored by EMC [2].
