The
results here were very impressive! It even outperformed our Yamaha
CRW-F1. The max transfer speed was 40.60x which is what the drive is
rated at. Seek times and CPU usage were very low. Much lower
than our CRW-F1.

The
transfer speed tests on the CDR were lower due to a small spike. I ran
the test 3 times and there was still one spike at some point during the test.
The seek times and CPU usage scores were slightly better than those from the
pressed CD.

4.
DAE Quality Test
For
these test, we used a 64min compilation CD.
DAE quality score was a perfect 10 on the both
the pressed CD and CDR.
5. DAE- Advanced Quality Tests
The drive performed fairly well in these tests
with a quality score of 100. It passed all on the fly copying tests
except at 16x. Unlike our Yamaha CRW-F1, it did read CD Text, however,
it was unable to read both the Leadin and Leadout.
