Apparently they mistyped it, probably the dork writing the article didn't know that there is a difference between MB and Mb.mjrpes wrote:DVDs read at 10.8 megabits per second at 1x speed. We now have DVD players that can read at 16x, so that's theoretically 172.8 megabits per second, which is .69 times slower, not 20 times.InPhase says the technique could theoretically be used to store up to 1.6 terabytes of data on the same size of disc and to read data at 120 megabits per second. This is 340 times the capacity of an ordinary DVD and 20 times the data rate.

"Holographic media, the two companies said, has storage capacities achieving 1.6 TeraBytes per optical disk and data rates as high as 120 MBPs."
Ah, thanks for the clarification. That's a very nice transfer rate.MidnightQ4 wrote:Apparently they mistyped it, probably the dork writing the article didn't know that there is a difference between MB and Mb.mjrpes wrote:DVDs read at 10.8 megabits per second at 1x speed.

Odd, though. 120 MBps is much faster than any current HDD. Why is this technology being marked as a replacement for DVDs, when it could be a replacement for HDDs?

Probably because it doesn't have as fast of a random access time? Also that is the projected speed that it will attain later on after release. And actually it is being billed primarily as a replacement for large tape backup systems initially, for enterprise data warehouses. Of course it would have a lot of other uses too.
