4. DVD Reading Tests

DVD reading tests

- Single Layer PTP DVD-ROM (Click for CDSpeed results)

The CyberDrive DX082D supports 12x CAV reading speed with single layer DVD-ROM media. From the diagram above it can be seen that the drive managed to surpass the manufacturer's stated DVD reading speed of 12x specifications, as well as being the fastest of the four drives.

The performance of the CyberDrive was very good in this test. In comparison with the other drives, it has the fastest full seek time, while its random and 1/3 seek times place it somewhere in the middle.

- Dual Layer PTP DVD-ROM (Click for CDSpeed results)

The two layers of a PTP DVD-ROM disc are read sequentially with the drive starts reading from the inner tracks of the disc, which is the beginning of each layer, moving towards the outer tracks for each layer.

From the graph above it can be seen that the CyberDrive produced the same performance as the Philips drive, probably due to the use of the same chipset. However, Optorite was the fastest in this test with Plextor second.

Although the CyberDrive wasn't the fastest in the DVD dual layer speed tests, the same doesn't hold true for the seek time tests for the same media. According to the graph above, the CyberDrive had the best times in all modes. Especially in the full seek times, where it was faster than the second placed drive by 11ms.

- Dual Layer OTP DVD-ROM

The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc tested previously. The difference here is the reading strategy of the second layer of the disc. The beginning of the second layer is located in the outer tracks of the disc, so that the drive starts reading from the outer tracks toward the inner tracks.

In the following screen shot from Nero CDspeed, it can be seen that the drive performed smoothly over the entire surface. It started reading at 3.15x and finished at 7.61x having an average speed of 5.67x.

- DVD Ripping Tests

We measured the DVD-Video ripping speed of the CyberDrive DX082D using the latest version of DVD Decrypter software. The DVD Video title was the "Matrix" pressed DVD (single layer, 4.38GB).

The CyberDrive ripped the DVD movie files to the hard disk at 7489 KB/s (5.4x) average. It is not the best time but is still good. Philips had the fastest performance and Plextor the slowest.

It should be mentioned that although the Plextor PX-708A supports 2x DVD Video ripping by default, pressing the eject button for 3 seconds (no disc inserted) will enable DVD ripping at higher speeds. In this case, the average ripping speed for the same movie reached the 8,957KB/sec (6.5X).

- DVD Recordable / Rewritable reading Tests

The chart below shows the Nero CDSpeed results with the following media:

From the above graph, we can easily conclude that all drives exhibited similar performance since the differences in maximums does not exceed more than 0.2x. CyberDrive had the second best reading speed after Optorite. In this typical comparison, Philips was third and Plextor fourth but once again we mention that the differences was negligible.
