CD Read Tests
Let's take a quick look at the test system specs before we begin with
testing. Keep in mind that performance may vary depending on the
hardware you use, particularly the speed of your hard drive. This is why I provide full specs for comparison.

The
DW1640 was capable of hitting its max read speed of 48x and overall results
were very impressive. With our pressed CD, the seek times and CPU
Usage were super low.
2. CD-DVD Speed - CD-R
|
Test Results |
|
Transfer Speed
Average: 36.74x
Start: 20.95x
End: 48.44x |
|

1X: 1%
2X: 1%
4X: 3%
8X: 6% |
Again, we see some excellent read performance with CD recordable media.
Max read rate was just over 48x with an average of about 37x. Seek
times and CPU usage generally remained low as well.
3. CD-DVD Speed - CD-RW
|
Test Results |
|
Transfer Speed
Average: 31.18x
Start: 17.63x
End: 41.36x |

8X: 6% |
Most of the writers I've reviewed tend to struggle a bit with CD rewritable
media. However, the DW1640 performed exceptionally well, easily
hitting 40x read rates and once again showing some incredibly low seek
times.
4. DAE - Advanced Quality Tests
The BenQ DW1640 performed exceptionally well
in our advanced digital audio extraction tests. Its average speed was
fairly high when compared to other drives we have looked at. It passed
all on-the-fly copying tests, including those at higher 12x and 16x speeds.
The DW1640 was only unable to read the Lead-out info on the disc.
