60 DVDs per second...

GizMag article

"German and Japanese scientists recently collaborated to achieve just such a quantum leap in obliterating the world record for data transmission. By transmitting a data signal at 2.56 terabits per second over a 160-kilometer link (equivalent to 2,560,000,000,000 bits per second or the contents of 60 DVDs) the researchers bettered the old record of 1.28 terabits per second held by a Japanese group. By comparison, the fastest high-speed links currently carry data at a maximum 40 Gbit/s, or around 50 times slower."

1 CD of 700 Megabits;
Bits = 700 000 000
Kilobits = 700000
Gigabits = 0.7
Terabits = 0.0007
