10 DVD Burners: 16x and Dual-Layer - or Nothing!

BenQ DW-1620

If you want to get a DW-1620 from BenQ, there are two ways to do it. The easier way is simply to buy one directly. The other option is to take a DW-1600 and flash it with the latest firmware available. This will add DVD-R and DVD-RW writing capabilities to the DW-1600, which were unavailable when the product was launched. Then all you have to do is flash it again with the latest firmware for the DW-1620, and you're good to go!

To improve its burning qualities, the BenQ uses the WOPC (Walking Optimal Power Calibration) system. WOPC lets the DW-1620 optimize the recording quality throughout the write process by adjusting the power of the laser. To avoid buffer underruns, the DW-1600A uses Seamless Link technology.

    Please report noise levels in optical drive reviews. This is a big factor in which drive to buy for some people. My current DVD burner sounds like a jet engine for 5 minutes after putting a disc in.
