We've been hearing rumblings of holographic drives and media for years, but now they're actually on the way, ready to be shipped this year. We saw some of these holographic storage prototypes at CES, where 515GB of data can be shoehorned onto a square inch of disk space.
What's the catch? The first wave of products will use a red laser, not the blue or green laser that will give us the most incredible densities. First out of the gate will be 300GB disks with a disappointingly slow 20MB/second transfer rate. And of course, this technology will be expensive at first. Even so, we can't wait to see those
green and blue laser multi-terabyte holographic disks, small and lightning-fast.
