As of April 2012, no storage system has achieved one zettabyte of information. The combined space of all computer hard drives in the world was estimated at approximately 160 exabytes in 2006. This has increased rapidly however, as Seagate reported selling 330 exabytes worth of hard drives during the 2011 Fiscal Year. As of 2009, the entire World Wide Web was estimated to contain close to 500 exabytes. This is a half zettabyte.
