Hitachi figured that if one Blu-ray disc holds 50GB of data, why not stack 100 super-thin discs on top of each other and cram them into a 2.5-inch thick cartridge? The result: 5TB of storage. That's just what the company is going to do with its SVOD (Stacked Volumetric Optical Discs) technology.
Talk about floppy! These new "blue-violet laser" disks is actually made of a very thin film and hold about 9.4 GB on each side. The really draw is that they've figured out a way to put 100 of these in a cartridge for almost a terabyte of storage.
