What are HVDs?
HVDs are holographic versatile discs. They are one next-generation storage technology currently in the research phase. HVDs are specified to store as much as 3.9 terabytes (TB) of data, which is equal to 3,900 gigabytes (GB), or nearly 4 million megabytes of information. The data transfer rate of HVDs is 1 gigabit per second, which is equivalent to 128 megabytes per second, or more than six times faster than high-speed DVD players. Some people refer to HVDs as next-next-generation, as the technology they are surpassing has yet to become widespread. Both Blu-ray discs and HD DVD offer storage capacities and speeds far greater than DVDs, and both are eclipsed by the specs of HVDs. HD DVDs have storage capacity of 15 GB in a single layer, 30 GB in a dual layer, and 45 GB in a triple layer. Blu-ray discs have a storage capacity of 25 GB in a single layer and 50 GB in a dual layer. Neither come anywhere near to the enormous capacity of HVDs. HVDs are expected to hit the market during 2006,
