It has been been something of a digital philosopher’s stone since the ’60s, promising infinite storage and massive data rates. When a holographic storage prototype was finally demonstrated at NAB 2005 by InPhase Technologies, many of us couldn’t believe that we might actually be standing on the cusp of a storage renaissance. In 2010, though, with no further public demonstrations, $100 million spent, 10 years of R&D, and commercial viability remaining elusive, InPhase ran out of money and shut up shop. Well, good news: InPhase’s assets have been bought up by a company called HVault, and it’s currently demonstrating its holographic storage tech at NAB 2012 in Las Vegas, with the apparent target of replacing petabyte, hard-drive-based storage clusters. Better yet, HVault’s tech will apparently launch in “spring 2012.""
