Holographic Storage Slated to Hit Market This Fall 201
prostoalex writes "The Guardian takes a look at the current developments in the world of holographic storage. Despite being available in research for over 40 years, the technology is getting commercialized only now, with InPhase Technologies launching its 600 GB write-once disk and a drive this fall. What avout the price? "The first holographic products are certainly not mass-market — a 600GB disc will cost around $180 (£90), and the drive costs about $18,000. Potential users include banks, libraries, government agencies and corporations.""

Bleeding edge is always a ridiculous expense. The people who are willing to be there already know who they are. That you even raise this question means that you are not.
OTOH, neither am I, but that's not the point. The point is, this is the first commercial volley of a new technology, which means that a few years hence it will be cheaper with even higher data densities.
Meaning, potentially, something like the entire run of every season of every Star Trek series ever... on one disc.

If that's the speed, then it absolutely isn't a good reason to use this.
The only advantage this actually has is information density. One 600GB disc is going to be pretty tiny compared to an array of harddrives designed to get the speed up.
Is that worth it for a library or bank? My inclination would be no. A couple hundred harddrives in a SAN is probably a better idea.
