LTO3 Ultrium Data Cartridge features a 400GB native storage capacity (800GB using 2:1 compression) and a sustained native transfer rate of up to 80MB/second (160MB/second compressed). Combines the advantages of linear multi-channel, bi-directional formats with enhancements in servo technology, data compression, track layout and error correction. Proprietary Advanced Alloy Armored Metal Particle (A3MP) technology provides better protection for your most valuable data. A3MP uniformly coats the metal particles with alloys and ceramics to provide high-output characteristics, maintain a high resistance to environmental conditions, and reduce variations in particle size when compared to conventional materials.
