LTO technology is an “open format” technology, which means
that its users will have multiple sources of product and media.
The “open” nature of LTO technology enables compatibility
between different vendors' offerings by ensuring that vendors
comply with verification standards. The LTO technology is
implemented in two formats: the Accelis format focuses on fast
access; the Ultrium format focuses on high capacity. The Ultrium
format is the preferred format when capacity (rather than fast
access) is the key storage consideration. An Ultrium cartridge
has a compressed data capacity of up to 800 GB (2:1
compression) and a native data capacity of up to 400 GB.
