DVD Read Tests
BenQ
drives do not have a rip lock in firmware. This should result in some
rather impressive read performance with DVD media. Let's have a look...

performance on single layer DVD-Video was about as good as it gets. Its
quite a speedy drive, able to easily hit 16x read speeds. Seek times and
CPU Usage were very low. The results here are the best I've seen yet on
a 16x drive.

With
dual layer PTP discs, the results were fairly similar in comparison to their
DW1620. Seek Times, however, were lower. Its max read rate was
just under 7x. This is not that bad and should be a decent ripper, as we
will test later.

Performance with dual layer OTP discs was excellent and almost identical to
the DW1620. Once again though, we do see an improvement in Seek Times.
Very good results here.
4.
CD-DVD Speed - DVD-R, DVD-RW, DVD+R, DVD+RW
To capture maximum transfer rates of recordable media, I gathered up some
discs of all formats.
The results were once again, very similar in
comparison to the DW1620. 8x seems to be the max read speed with
recordable media.
