Data CD Reading Tests

- Pressed CD results (Click for CDSpeed results)

The Optorite DD0401 drive supports a maximum reading speed of 40x for the CD-ROM format. The pressed disc was read using CAV mode and gave an average speed of 30.44x. The graph above shows that the Optorite drive was the slowest among the three drives, however the results are still satisfactory. The reading speed reached a maximum of 40.29x at the end of the reading process.

On the seek times test the Optorite DD0401 gave the fastest results among the three drives. The random seek was better than the manufacturers specifications with 84ms while the drive needed 147ms for the full seek test.

- CD-R Media results (Click for CDSpeed results)

The Optorite DD0401 CD-R media read results were similar to those of the pressed disc. The reading method was again CAV and the reported start speed was at 17.25x. As with the pressed disc, the Optorite drive was slower in comparison with the Plextor and Philips drives.

However, in the seek times the Optorite drive was again fastest. The Random seek time returned 79ms, a value that is much lower than the manufacturer's specifications (100ms). The graph above shows conclusively that the Optorite drive is faster than Plextor and Philips on the seek times test.

- ReWritable Media (Click for CDSpeed results)

The Optorite DD0401 supports the 40x reading speed with CAV mode using rewritable media. For the reading test we used 24x High Speed rewritable media from Mitsubishi Chemicals.

The performance with CD-RW was not all that different than that with CD-R media. The disc was read under CAV mode and the reported average reading speed was 30.65x.
