Annual sales of storage capacity will grow by more than 30  percent every year between 2013 and 2017, according to a forecast the  research company announced on Monday. But that growth will be slower  than the steep pace recorded a few years ago because organizations have  adopted ways of using storage more efficiently, including cloud storage  services, IDC analyst Natalya Yezhkova said.       Data deduplication, data compression, thin provisioning and  storage virtualization all will help enterprises limit their purchases  of new storage capacity, Yezhkova said. Those techniques can reduce the  amount of space consumed by a given bit of information or help companies  allocate new storage as needed instead of overbuying.       IDC estimates more than 102 exabytes of external and 36 exabytes  of internal storage system capacity will be sold in 2017, up from just  20 exabytes of external and 8 exabytes of internal capacity in 2012.  External storage sits outside of servers, while internal goes inside  them.       That means the average amount of storage space companies acquire  will grow by an average of 35 percent to 40 percent per year for  external storage and 33 percent to 38 percent for internal, IDC said.  That rate should stay pretty constant all through the forecast period,  according to Yezhkova. In terms of enterprises' storage spending, the  annual average growth rate will be 4.1 percent, hitting US$42.5 billion  in 2017.       Though fast, the annual growth rate from 2013 through 2017 will  be dramatically slower than what it was before new efficiency techniques  took hold, she said. Enterprises added 65 percent more storage space in  2005 and 59 percent in 2006 and 2007, according to Yezhkova. She went  back to those years for comparison because the world financial crisis  distorted storage spending from 2008 to 2011.       Part of the reason enterprises will be adding capacity more  slowly in the coming years is that some will send their data to cloud  storage services, Yezhkova said. If those cloud providers buy drives  directly and assemble their own storage systems, they don't show up in  this IDC forecast. Google, for example, builds its own storage systems,  she said. Among enterprises, only the largest ones with the biggest IT  staffs would take that approach, Yezhkova said.       However, when companies shift some of their storage to cloud  services, they are putting it on infrastructure that's typically more  efficient, she said. Because they're in the business of storage, cloud  providers run a tight ship.       Also in its report, IDC said developing countries are on their  way to outpace more mature economies in storage spending. This will be  largely because of faster economic growth in those countries, Yezhkova  said. For example, IDC expects the region of Central Europe, Middle East  and Africa, which includes growing Eastern European economies, to  surpass Japan's storage spending next year. By 2015, the Asia-Pacific  region, excluding Japan, will pass up Western Europe, IDC said.       IDC is a division of International Data Group, the parent company of IDG News Service.
