Data CD Reading Tests

- Pressed CD (Click for CDSpeed results)

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 CDSpeed results)

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 CDSpeed results)

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.
