Pioneer DVR-A05

4. DVD Reading Tests

Pioneer DVR-A05 IDE DVD-R/-RW - Page 4

DVD reading tests

- Test Method

We used Nero DVD Speed to run DVD tests. All tests were performed at least 3 times with the same DVD title (we show the average results). The tests discs were one single sided, single layer DVD-ROM, one single sided, dual layer DVD-ROM, and DVD-R,-RW, +R and DVD+RW media. Also we used 4X DVD-R and 2X DVD-RW media (maximum allowed writing speeds).

- Single Layer DVD-ROM reading: (Click for DVDSpeed results)

Pioneer DVR-A05 supports 12X CAV maximum reading speed for the DVD format. The drive is clearly faster than the previous model.

The seek times of DVR-A05 are also improved. The random seek test gave an 128 msec result, and the Full seek around 300 msec. The results are confirmed by the Pioneer specifications.

- Dual Layer DVD-ROM reading: (Click for DVDSpeed results)

The drive supports 8X CAV reading speed for the dual layer DVD-ROM discs. The DVDSpeed graph states that the change layer time is 386msec. Something that we found interesting is the reading strategy of the drive in the second layer. The transfer rate graph looks the same as in the first layer, but the rotation speed seems not to be constant, since the drive slows down in the beggining of the reading process and accelerates until the end of the task.

The seek times for the dual layer DVD-ROMs are the same as in the previous test.

- DVD Ripping Tests

We measured the DVD Ripping speed using the "Matrix" DVD Video title and DVD Decrypter v3.0 software.

The ripping speed of the DVR-A05 seems to remain the same as in the previous model, around 2750 kb/sec. The drive is not the fastest you can find forthis test and the performance could be higher.

- DVD reading Tests

The charts below shows the Nero DVD Speed results with the following media.

In this chart you can see the average reading speeds for the A05 with 2X and the newer 4X DVD-R media. The drive supports 6X CAV average reading speed for the 4X media and 2X CLV for the 2X DVD-R discs. Notice that X equals to 1.38 MB/sec for the DVD format. The average reading speed for the 4X DVD-R is 4.61X. In addition, the drive supports 6X CAV average reading speed for the new 2X DVD-RW media.

Pioneer can also read the DVD+RW /+R discs, at a reasonable speed. The DVD+RW disc was read at 4.8X and the DVD+R at 9.29X!
