Data CD Tests

- Pressed CD results (74min and 80min CD Speed Graphs)

Panasonic LF-D521 supports 32x CAV CD reading speed. In our test, the drive reached the 36.73x by the end of the disc, resulting to an increased average speed of 27.72x. The Pioneer DVR-A05 performed as it was expected and gave an average speed of 24.84x.

According to the specifications of the Panasonic drive, the average seek time is around 120msec. The drive performed well in all the seek modes. The Pioneer A05 is slower in the 1/3 and full seek tests.

- CDR Media results (74min and 80min CD Speed Graphs)

The Panasonic drive was again faster than expected with CD-R media. The average reading time is 27.8x, while the DVR-A05 improved the average reading over the previous test speed by 1x.

In the seek test, the results were not different than in the pressed CD test.

- HS-RW media (Click to see the CD Speed Graphs)

For the RW tests we used the Plextor HS-RW media. The LF-D521 started reading at 12.16x and finished at 27.74x, resulting to 20.97x average speed. The drive supports 28x CAV reading with RW discs. The Pioneer drive is faster with an average of 25.5x.
