Data CD Reading Tests
- Pressed CD results (Click for CDSpeed results)
The Pacific Digital U-30201 drive supports 40x CAV reading speed with both CD-ROM and CD-R media. The maximum speed reached in our CD-ROM reading test was 41.65x on the outer tracks of the disc, with an overall average speed of 31.43x. The results are quite good, although the LiteOn drive was slightly faster.
On the seek times test, the Pacific Digital drive performed quite well being only slightly slower than the Optorite drive as can be seen from the graph above. The average reading speed was 108 ms which is good, however again the Optorite DD0401 proved to be the best performer with 84msec for a random seek.
- CD-R Media results (Click for CDSpeed results)
In the transfer rate test for CD-R media, the Pacific Digital drive returned results very similar to those for the transfer rate test for CD-ROM media, as was the case with the other two drives. The start speed was 18.02x, end speed 41.61x and average of 31.32x. Here, the Pacific Digital drive had the fastest average speed among the drives although there was very little between them.
The seek times for the Pacific Digital drive were very close to and slightly better that those for the LiteOn and a little slower than its comparative times for CD-ROM media. In contrast, the Optorite drive had faster CDR-Media seek times than for CD-ROM media and was overall with seek times.
- ReWritable Media (Click for CDSpeed results)
The Pacific Digital U-30201 supports a maximum reading speed of 24x CAV with rewritable media. For the reading test we used 24x High Speed rewritable media from Mitsubishi Chemicals.
The reading speed with CD-RW media was quite good although slower than that with either CD-R and CD-ROM media. The drive returned an average read speed of 25.39x while only managing a final speed of 33.67x. Only the Optorite drive managed to surpass 40x (40.64x) and appears to be the fastest reader from the three.
