SAIT is based on advanced helical-scan recording technology, which is known for its high data density, outstanding data transfer performance, as well as reliability and durability advantages. SAIT's use of Advanced Metal Evaporated (AME) media and helical-scan recording technology results in much higher capacities than what is possible through conventional tape technologies. By utilizing an industry standard half-inch media form-factor, SAIT is able to store over twice the capacity and provide compatibility with many popular automation solutions.
