TAL K IN G P OI N T S gone to that meeting armed with data about using solid-state disk (SSD) for the organization's backup and archive needs, but "he schooled me on tape versus spindles," Ricco said, adding that he learned a lot that day about the advantages of adding digital tape to the mix of storage technologies because of its high density, energy efficiency, and low total cost of ownership. Many industries with large data storage requirements maintain that tape has never ceased being integral to maintaining costs in enterprise backup and archive operations. For these businesses, tape represents a mature medium, one well suited to low-cost, long-term storage of large quantities of data, and, not incidentally, one that in orders of magnitude may be more reliable than SATA and enterprise disk. Tape offers tremendous advantages, including cost savings. The Clipper Group did a study showing the total cost of ownership of a disk system is 15 times higher than that for tape for storing the same amount of data in both systems over 12 years. The energy need to store data on disk during this time period is 238 times higher for a disk system than it is for tape. It's easy to underestimate the energy costs of keeping disk spinning continuously and cooling the disk system. ROI of surveillance video Prior to recent innovations, conventional wisdom held that "Surveillance is a cost that can never be turned into a profit." Only five years later, this statement is no longer true. Today's data analytics tools—some of which are Evolution of storage technologies ■ Tape storage ■ Disk storageCloud storage — DVR/NVR (Networked video recorder) — Scale-out Network Attached Storage (NAS) ■ Flash/SSD storage ■ Edge storage: video data stored on-camera or at the "edge" of the Ethernet network even built into the surveillance camera itself—can extract information about customer behavior, internal processes, and trends, to generate or increase ROI.
