![]() Mellor indicates that there seems to be an average 2.5 years between commercialization of successive LTO drive standards, which leads to the following table: LTO Generation ProgressionĬurrent generation LTO-8 cartridges take at least 9h16 to fill, with predicted speeds on future drives increasing that even further. Recent generational increases in LTO tend to double the capacity, so we’re looking at LTO-13 for 384 TB drives. In standard LTO nomenclature, we are currently on LTO-8 where the drives have 12 TB raw capacity. This enables for much smaller particles to be placed into tracks, and thankfully according to Fujifilm, Strontium Ferrite exhibits properties along the same lines as Barium Ferrite, but moreso, enabling higher performance while simultaneously increasing particle density. Strontium sits on a row above Barium in the periodic table, indicating a much smaller atom. ![]() Strontium Ferrite would replace Barium Ferrite in current LTO cartridges. Current drives are over an order of magnitude smaller, at 8 Gbit-per-square-inch, however the delay between research and mass production is quite significant. ![]() IBM and Sony have already demonstrated 201 Gbit-per-square-inch technology in 2017, with a potential release of the technology for high volume production in 2026. One of the two leading manufacturers of tape cartridge storage, FujiFilm, claims that they have a technology roadmap through to 2030 which builds on the current magnetic tape paradigm to enable 400 TB per tape.Īs reported by Chris Mellor of Blocks and Files, Fujifilm points to using Strontium Ferrite grains in order to enable an areal data density on tape of 224 Gbit-per-square-inch, which would enable 400 TB drives. ![]()
