The zebibyte is a multiple of the unit byte for digital information. It is a member of the set of units with binary prefixes defined by the International Electrotechnical Commission (IEC). Its unit symbol is ZiB.
The prefix zebi (symbol Zi) represents multiplication by 10247, therefore:
The prefix zebi was originally not part of the system of binary prefixes, but was added together with the prefix yobi by the IEC in August 2005.[1]
Usage examples
- GUID Partition Table (GPT) allows for a maximum disk and partition size of 8 zebibytes, or 9.4 zettabytes, when using 512-byte sectors.[2][3]
- The ZFS filesystem has a theoretical volume size limit of 256 zebibytes.

Disk pointers are 64 bits in size, meaning that GPT can handle disks of up to 512 x 264 bytes (8 zebibytes, or 8.6 billion TiB), assuming 512-byte sectors.
