Data CD Reading Tests
- Pressed CD results (Click for
For this test we used an 80min data pressed CD-ROM disc. When the reading
test ended, NeroCDSpeed reported that the Optorite DD0405 read the disc under
The above graph shows that all drives returned almost the same speed
with the Memorex being a little faster with all measurements. The Optorite
was the slowest among the three drives but the reported speed meets the manufacturers
for 40x maximum reading.
Apart from the reading speeds, NeroCDSpeed reported the seek times
for the drives and we present them on the above graph. The Optorite DD0405
fast. The drive gave back the fastest seek times among the three drives, in
all three modes. The drive finished the full seek test in only 146ms while
the Memorex needed 286ms for the same task.
- CD-R Media results (Click for
On this test we checked the reading performance of the drive with CD-R
media. The disc used is a clone of the previously tested pressed media. On
the transfer rate test of CD-R disc, all three drives had almost the same results
as with the previously tested pressed media. The Optorite DD0405 read the CD-R
under CAV and returned again the slowest reading speed among the drives.
The drive finished the test with an end speed of 40.31x verifying the
40x maximum reading speed for CD-R media.
Once again, with the seek times tests with CD-R media, the Optorite proved
to be very fast, having seek times similar to that with CD-ROM media. The drive
needed 81ms, 97ms
147ms for random,1/3 and full seek times respectively.
- ReWritable Media (Click for
For the rewritable reading test we used 24x High Speed rewritable media from
Mitsubishi Chemicals. With the rewritable format, the Optorite supports 40x
reading speed while both Memorex and Nec support 32x and therefore Optorite
the test with the fastest speeds. Once again, the Optorite drive read the disc
under CAV mode and the test finished with an end speed of 40.64x.
