What is the capacity of an iVDR?
Aļ¼There are currently four standard iVDR types available: 500 GB, 320 GB, 250 GB and 160 GB. 500 GB is equivalent to about 107 DVD discs (single-sided single-layer type = 4.7 GB per disc), or about 20 Blu-ray discs (single-sided single-layer type = 25 GB per disc). The capacity of hard disks is increasing by some 40 percent annually, and accordingly iVDR capacity is also expected to increase annually. A 1TB iVDR is expected to be launched in 2011.
