Data CD Reading Tests
- Pressed CD (Click for
In this pressed CD reading test, there wasn't much between the drives with
the LiteOn LDW-811S being marginally faster.
With a final speed of
40.37x, the SONY drive confirms the manufacturers specifications for 40x reading.
Again, the Sony and Optorite drives had similar times with the Sony being
slightly slower, and both being faster that the LiteOn, especially in the full
seek where the LiteOn needed 200ms for the Full seek.
- CD-R (Click for
We made a copy of the previous pressed CD in order to test the drive's behavior
with a CD-R media. The resulting speeds are very close to those of the test
with the original pressed media from above. This is good, steady behavior
with different media from all three drives.
Here too, the seek times are almost identical to those of the same test
with the original media and again the Optorite drive returned a very slow
full seek time.
- ReWritable Media (Click for
For the reading test
we used 24x High Speed rewritable media from Mitsubishi Chemicals.
Both the Sony and Optorite drives returned speeds very close to those of
the previous tests and both managed to reach 40x reading speed, something which
was not the case with the LiteOn which reached a final speed of 33.48x, however,
its specifications indicate 32x CAV with rewritable media. The times
for the Sony drive in general have been quite good and steady, and
the drive does not appear to be affected by the CD media type used.
