For every drive, somebody is bound to be disappointed, but on balance, BenQ 1620/25/40 have been very good drives, and 1655 is marginally better with the updated chipset. The best thing about BenQ/Philips drives has been their gradual improvement over time. With a couple of other major optical drive brands (which will remain unnamed), the general feeling has been that things have been going slightly downhill over the past 12 months.
Not at all, they’ve been coming at a good pace. BenQ has always been good with media support from the start, again, unlike several other manufacturers who release drives with very limited and incomplete media support. [A couple of notes here. First, what I said above does not apply to DQ60; it has a shorter media table than almost any other drive I’ve seen. Second, with SolidBurn, BenQ has largely removed the pressure to constantly update specific media support by making the burning process adaptive.]
Lightscribe support doesn’t take anything away, or even affect the regular data burning process. It costs about $10 extra in DW1655, but you don’t have to use Lightscribe. I have no interest in it, but feel DW1655 is well worth the extra $10 for its better 16x burns.
