A CD-size disk could store 500GB using this technology, with 1TB and greater capacity potentially possible in the 2011/2012 period.

This compares to InPhase's 300GB capacity, although InPhase has predicted a ramp up through 800GB to a 1.6TB capacity point and a 120MB/sec transfer rate. This was said to be appearing in 2010, but that was in 2007, so we'd better assume a 2012/2013 date if InPhase holds to its course.

This makes them, in theory, usable by consumers and thus increases their volume dramatically, compared to the professional archiving market addressed by Plasmon's UDO and the InPhase Tapestry development. 

We should bear in mind that GE is suggesting that consumer drives using its technology wouldn't appear until 2014 or 2015, though, suggesting that drive cost will be a problem in the early years.

At that speed, a 1TB GE technology disk would take 2.65 hours to write. 

Cost-wise, GE is suggesting 10 cents/GB or less for disk capacity when the drives and disks are introduced, as hopefully expected, in 2011/2012. At $0.10/GB, a 1TB disk would cost $100: far, far from cheap.

He also mentioned the notion of disks having the capacity of 100 Blu-ray disks, implying a 2.5TB or even 5TB capacity, gained by increasing the number of layers used for recording.

What is there to say that GE's holographic storage technology is not just the latest optical storage dust-biter? 

but GE's skin in the game is pretty thin and it has to talk up its technology, as it's got licensees to convince. A key is drive and disk volume and pricing.
