Increased write speeds have a direct impact on write times. The creation of a DVD-5 took 6:18 on the old 16x drive, 5:29 on the 18x model, and 4:13 on the more modern 24x drive.
Write speed was limited to 8x due to media availability. The 24x Sony Optiarc AD-7240S would be capable of writing double-layer discs at up to 12x, but we suspect the cost of doing so would be prohibitive, even if the necessary media were more readily available.
