Worldwide and U.S. Enterprise Storage Systems Forecast Update, 2017–2021This IDC study provides update to the worldwide and U.S. enterprise storage systems forecasts for 2017–2021 along with historical data for 2012–2016. The forecast and historical data focus on end-user consumption of three categories of enterprise storage systems — external, internal, and "other," which covers cumulative shipments of systems sold directly to customers by original design manufacturers. For each of these categories, IDC has estimated value (end-user spending), terabytes, and price per gigabyte."The enterprise storage systems market continues to evolve along with the entire IT industry to foster expansion of digital transformation initiatives and enable growth of fast-developing areas such as internet of things, artificial intelligence, and machine learning," says Natalya Yezhkova, research director, Storage. "Along with emergence of new storage technologies such as persistent memory storage, these developments also drive broader involvement of storage vendors in ecosystems serving new markets and creating comprehensive solutions spreading across multiple business and technology domains."
