Toshiba SD-M1712 DVD-ROM

4. DVD reading tests

DVD reading tests

- Test Method

We used Nero CD 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.

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

Toshiba SD-M1712 supports 6 to 16X CAV reading speed for the single layer DVD-ROM discs. The drive read the disc at 11.83X average speed, behaving in a similar way as Teac DV-516E. Toshiba SD-M1612 follows closely with 11.13X.

The seek times of Toshiba SD-M1712 are low for the DVD-ROM format. The random seek test gave a 92msec result, and the Full seek around 139msec. The Teac drive is slightly faster in the Random and 1/3 modes, with a small however difference. The performance was expected and the results are verified by the drive's specifications.

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

The drive supports 4.1-10X CAV reading speed for the dual layer DVD-ROM discs. It started reading at 4.25X and finished the task at 10.18X, with an average speed of 7.62X. The Teac drive is faster by 1X.

The seek times for the dual layer DVD-ROMs are slightly higher than with single layer DVD-ROMs.

- 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 Toshiba SD-M1712 is not very high and reaches the 5216 kb/sec (3.8X). The Asus and Teac drives are faster.

- DVD reading Tests

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

Toshiba SD-M1712 supports 2 to 4.8X CAV reading speed for the DVD-R/RW discs. The drive gave a 3.9X average reading speed for the DVD-R and 3.47X for the DVD-RW format. Although the drive does not officially support the DVD+RW and DVD+R discs, it finished our tests without any problem. In addition, the drive was gave the higher reading performance with DVD+R media. However, the Asus and Teac drives are generally faster. Note that the missing results in the graph (zeros) do not indicate any inabilities of the corresponding drives to finish the task. Unfortunately we did not have the chance to re-test the Asus E616 and Toshiba SD-M1612 with DVD+R media.
