Data CD Reading Tests
- Pressed CD results (Click for
The LiteOn LDW-811S drive supports 40x CAV reading speed with CD-ROM/-R.
The maximum speed reached was 41.83x on the outer tracks of the disc, with
an overall average speed of 31.58x. The results are quite good, although the
was slightly faster.
On the seek times test, the LiteOn drive returned the slowest times amongst
the three drives, especially the full disc seek which was a hefty 200ms,
while the random and 1/3 seeks were somewhat better.
The Optorite DD0401 was the best performer with 84msec
for a random seek.
- CD-R Media results (Click for
In the transfer rate test for CDR media, the LiteOn drive returned results
very similar to those of the transfer rate test for pressed CDs previously,
as was the case with the other two drives. The reading method was CAV, with
a start speed of
and average of 31.3x. Here too, the LiteOn drive was slightly slower than the
The seek times for the LiteOn drive were quite slow, a good deal more so
than the other two drives. In comparison to the pressed CD seek times,
the LiteOn drive's times were markedly up although the random seek time is
well within the manufacturer's stated seek time of 140ms. In
contrast, the Optorite and CyberDrive drives had marginally faster
CDR-Media seek times when compared to pressed CD media.
- ReWritable Media (Click for
The LiteOn LDW-811S supports a maximum reading speed of 32x CAV with rewritable
media. For the reading test
we used 24x High Speed rewritable media from Mitsubishi Chemicals.
The reading speed with CD-RW media was a good deal lower than that
with CD-R media. This is again in contrast to the other two drives whose reading
times stayed fairly constant regardless of the media type used. The average read
time of 25.29x for the LiteOn is quite slow when compared to the 30.65x and
33.08x for the Optorite and CyberDrive drives respectively.
