Data CD Reading Tests
- Pressed CD results (Click for
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.
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
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
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
(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
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.
