"This very situation exists in today's mid-sized data centres where new technologies are competing with tape, again, for the favours of an IT staff. Everyone involved is struggling to support a rapidly expanding storage base while protecting the assets of the enterprise."
The Tape Advantage
"Tape must continue to be part of the storage hierarchy given the features and functionality as compared with other storage technologies. The cost per GB of storage of tape is far less than SATA drives even without considering the cost of power. Factor in compression, which is often not considered in many of the cost justifications, and tape is not only more cost effective, it is also far greener than disk. Tape's other advantages (potential density roadmaps, performance, reliability, removability, scalability costs, ability to support WORM and encryption) make tape an important part of the storage hierarchy."
Tape Empowers the Data Centre
Mark C. Ferelli
"Cutting costs is the name of the game for every IT organization. While the industry objectives might be different, the systems that make things happen aren't. Understanding your energy requirements from both a cooling and power perspective will be key to reducing your infrastructure bills while keeping up with the ever-increasing demand for more. Appreciating the economy of energy in your tape infrastructure is part of that understanding. From the point of view of actual power draw, tape contributes to a more modest OPEX for enterprises of all sizes."
