Optical media has become less important as consumers leverage CDs and DVDs far less than in years prior, instead consuming music and movies by way of streaming networks. Concurrent with the growth of real-time data and the number of connected users is a steady increase in the amount of data stored, or “anchored,” in enterprise data and control centers to power the global datasphere, many of which will be cloud based. In fact, IDC estimates that the percentage of data in the datasphere that is processed, stored, or delivered by public cloud datacenters will nearly double to 26% from 2016 to 2025. Such clouds will process, store, or deliver not just IT services but also entertainment, grid telemetry, and telecommunications. Enterprise datacenters use a variety of storage media types including HDDs, and NAND flash-based storage (including emerging storage technologies similar to flash), with each playing an important role to support a broad range of storage workloads economically (see Figure 13).
