AIT stands out above other tape technologies for its innovative design, capacity, performance and durability with a scalable product family that can span the range from the desktop to the enterprise. Other competing technologies offer "point products" that provide solutions for a unique application band. AIT is unique in that it also offers complete read and write compatibility over three generations of products with the last two generations also providing the innovative "Write-Once-Read-Many" (WORM) data permanence feature.

AIT is a high performance technology due to its much shorter media and its "one-pass" recording nature. Some popular competing technologies will "shoe shine" tape over 50 times in order to completely fill the media. The AIT recording technology is also characterized by a very short "streaming recycle" time—enabled by its slow tape motion, which provides superior overall performance over a range of host data rates.

AIT's gentle tape motion, air bearing tape wrap and very low tension, together with the exceptional durability of Advanced Metal Evaporated (AME) media, make it an ideal, high duty-cycle automation solution. The Annual Failure Rate (AFR) data for the AIT family over the past several years has demonstrated an equivalent Mean-Time-Between-Failure (MTBF) of over 300,000 hours at 100% utilization.
