In
our pressed CD tests, the drive came short of its rated 48x speed, maxing at
45.32x. They were fairly close in comparison to the NEC ND-3500A.
Seek times were not the lowest, but definitely not the worst I've seen. CPU Usage
was low, with the exception at 8x where the drive seems to tie up some
additional resources.

With
CDR media, transfer rates were quite the same. However, there was a
significant improvement with Seek Times. Again, we see the same issue
with CPU usage at 8x.

CDRW
read performance with this drive was quite poor, showing a maximum transfer
rate of only 22.74x. Seek Times were roughly the same but oddly, the CPU
usage at 4x was highest.
4.
DAE - Advanced Quality Tests
The advanced digital audio extraction tests were
not that impressive either. While there were no errors reported and quality
score was 100, its average speed was lower than most other models. It
also couldn't keep up in our on-the-fly copying at 16x. The drive also
failed to read both the leadin and leadout info on the disc.
Overall, the results of our CD read tests
weren't the greatest, but let's see how well it does with DVD media.
