Conventional recordable DVD media stores data on a single 4.7GB plane (level) of the disc. On dual-layer DVD media, there are two recordable 'layers' which can both store up to 8.5GB of data. Today we're looking at MSI's new DR16-B dual-layer DVD burner. The DR16-B is capable of burning DVD+/-R media at a blistering 16x, DVD+/-RW at 4x and most importantly, dual-layer DVD media at 2.4x. Of course you can still burn conventional CD recordable media and the MSI DR16-B flies along at 40x for CD-R, and 24x for CD-RW.
