Fancy writing a DVD in 6 minutes? Well, you certainly can, with a seventh generation DVD writer from Sony. These new drives write at 16x, which many minds believe will be the physical recording limit of DVDs. This is because such a recording speed means that the disc spins at about 10,000 rpm, which is probably the highest speed the polycarbonate material of a DVD can handle. Sony's new drives are available as internal (DRU-710A) and external (DRX-710UL). Both support a range of write speeds up to 16x and Double Layer burning at 2.4x.
