Is there room for more new tape technologies? It seems unlikely. No
matter how well designed and well engineered a new tape technology
might be, it will require a significant new value proposition in order to
gain a foothold in the market.A new format would have to offer far
greater capacity or two to three times the speed of Quantum’s
DLTtape system in order to have a big impact.In reality, the new tech-
nologies challenge DLTtape technology in some areas,but not in all.
DLTtape technology also has a huge amount of“head room”in terms
of scalability and an extremely well defined technology road map.So
even if a new technology offers a short-term performance benefit
today,in all likelihood that advantage will disappear as the DLTtape
system continues to evolve.The new generation of DLTtape systems,
Figure 1-6 DLTtape Drive Comparison Chart shows some of the important speci-
fications for DLTtape systems, including the industry-leading Super DLTtape system.
