Data CD Tests

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

Both Philips JR32RWDV and INcoder GH32U-A1 drives support the 40x CD-R reading speed. The Philips drive gave an average reading speed of 30.71x. Although the drive started reading at 7.94x, it accelerated very fast to 18x at the 1:30 min of the disc! With 74min media, the reading speed by the end of the task reached the 40.32x.

The drive gave low seek times in all three seek modes. It needed 101msec for the random seek and 158msec for the full seek mode. The INcoder drive was slightly faster in the same modes, but the differences should not be considered as important.

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

The JR32RWDV read the CD-R disc faster than the pressed one in the previous test. The drive's average speed is 31.73x, as it reached the 42.34x by the end of the process.

In the seek test, the drive was 10msec slower than a pressed disc in the random stroke, and exhibited good performance in the 1/3 and Full stroke tests.

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

For the RW tests we used the Ricoh HS-RW media. The JR32RWDV supports 40x HS-RW reading speed. The drive was fast and finished with a 31.66x average speed. The INcoder drive is slower due to its lower supported speed.
