1.
CD-DVD Speed - Pressed CD
For
the CD read tests, I used a CD that was just under 76min in length in order to
properly capture its maximum read speed. The same disc was copied to a
CD-R and CD-RW for further testing.

With
the pressed CD, the DW1625 was able to reach its maximum 40x read speed.
The seek times were very good and an improvement over their previous model.
CPU Usage rates were about the norm.

With
CDR media, the results were very impressive. It was able to hit a 41x
read rate and the seek times were very low. CPU Usage was the same as
the results from the pressed CD.
3.

I've
found that most drives tend to struggle a bit with CDRW discs. However,
the BenQ DW1625 handled these discs exceptionally well. Again, the drive
had no problem hitting its max read rate and seek times were once again very good.
4.
DAE - Advanced Quality Tests

The DW1625 did fairly well in the audio
extraction tests, but could not keep up with on-the-fly copying at higher
speeds. Leadout info could not be read on disc.
