Dual-layer DVD media is supported with write speeds of up to 8x, DVD-RAM support is available up to 14x, DVD + and - R are supported at up to 20x while + and - R/W are supported at 8x and 6x respectively. Moving on to old school CD support, CD-R writing is available at up to 48x, with R/W support at 32x. Of course, it's worth remembering that many of these quoted speeds are in fact variable during the writing process, thanks to the use of CAV (Constant Angular Velocity) and the like, so you frequently won't be seeing these maximum speeds throughout the writing process as we'll see shortly.
