Holographic storage promises immense storage densities and capacities with fast access times. InPhase, according to VNUnet has demonstrated over 500GB of capacity per square inch. InPhase is claiming they will ship drives with removable holographic disks with 300GB capacity and 20Mbps transfer rate later this year.

I love holographic technology and wish InPhase the best, but I don’t believe they have a viable business with their technology – yet. The problem: 3.5″ disk drives will reach 750GB by the end of this year with much faster transfer rates. InPhase’s 20 Mbps is only 2.5 million bytes per second or only 9GB per hour. It will take over 30 hours just to fill one disk! I predict that hard drives will still be more convenient and fairly cost-competitive than this promising new technology.

But keep at it guys. Lightning will strike if your investors are patient enough.
