With billions of devices already connected to the Internet, the data that they generate is set to grow at an explosive pace. In fact, a research by IDC finds that by 2020, the total amount of data generated will be close to 44 zettabytes (1 ZB equals 1 trillion gigabytes). As such, user demands for powerful storage solutions will be stronger than ever. One perplexing issue, however, is the perpendicular magnetic recording (PMR) technology most prevalent today is approaching its inherent physical limits. Manufacturers therefore are scrambling for next-generation storage technologies that increase density and capacity while reducing weight and power consumption. In this regard, Product Adopted:Storage
