(company, storage)
A company and, by extension, a tape format for computer data backup and transfer. The tape is a data quality 8mm video cassette recorder tape. Exabyte units can store between five and fourteen gigabytes of data per tape. Exabytes are usually attached to Unix workstations.


2^60 = 1,152,921,504,606,846,976 bytes = 1024 petabytes or roughly 10^18 bytes.

See prefix.


(1) One quintillion bytes. Also EB, Ebyte and E-byte. For example, Cisco reported 30 EB of global mobile data in 2014 and forecast nearly 10 times that much for 2019. See exa, binary values and space/time.

(2) (Exabyte Corporation, Boulder, CO, www.exabyte.com) Founded in 1985, for many years it was one of the world's leading providers of tape drives and tape storage products. Its high-capacity 8mm tape drives, introduced in 1987, have long been sold through OEM and reseller partners. Exabyte used to offer QIC and DAT drives from acquisitions made in the early 1990s.

2006 Acquisition
In late 2006, Norway-based Tandberg Data, itself a well-known manufacturer of archival and storage products, acquired Exabyte and all rights to its breakthrough VXA packet technology.

The VXA Alliance
Along with Imation, Sony and TDK, Exabyte was a founding member of the VXA Alliance, an industry group that focuses on the VXA packet tape format. VXA is a technology that restores and backs up data by reading and writing discrete packets, rather than by sequential linear tracking. Fourth generation VXA products double data capacity to 640GB (compressed) with a data transfer rate of 48MB per second. For more information, visit www.vxa.com
