Linear Tape-Open (LTO)Linear Tape-Open (LTO) technology was developed jointly by HP, IBM and Quantum to provide a clear and viable choice in backup tape storage options. The Ultrium format is the high-capacity, single-reel implementation of LTO Technology. It is ideally suited for backup, restore and archive applications and provides excellent performance and reliability in both stand-alone and automated environments. It is the preferred format when capacity and high streaming data rates are the key storage consideration. LTO Ultrium technology is an "open format" technology, which means that users will have multiple sources of product and media. The "open" nature of LTO technology also provides a means of enabling compatibility between different vendors' offerings. An Ultrium format Generation 4 cartridge has a capacity of up to 1.6 TB (2:1 compression) and up to 800 GB native, while the Ultrium format Generation 3 has a capacity of up to 800 GB (2:1 compression) and up to 400 GB native. Capacity for LTO Ultrium Generation 2 format cartridges reaches up to 400 GB (2:1 compression) and up to 200 GB native.
