One terabyte (TB) of data onto a single optical disc is the goal of the Holographic Versatile Disc (HVD) Alliance, a consortium to promote HVD technology.

The consortium said a 1 TB HVD disc could hold as much data as 200 standard DVDs and transfer data at over 1 gigabit per second, or 40 times faster than a DVD.

However, the initial assignments of the technical committee involve coming up with standards for a 200GB recordable disc and a 100GB read-only disc.
