Toshiba SD-R1202 CD-RW / DVD combo

2. CD / DVD Data Tests

TOSHIBA SD-R1202 COMBO IDE CD-RW/DVD-ROM - Page 2

CD / DVD Data Tests

- SCSI Mechanic v3.0x results

For the CD data tests we add the results of some 16x recorders, for comparison reasons. As it was expected for a combo CD/DVD drive, Toshiba SD-R1202 gave the best transfer rates in the Random I/O test. In the Sequential reading mode the drive was fast but PlexWriter PX-W1610A and Lite-On 16101B are slightly faster. The Same Sector I/O test gives Toshiba the third position.

- Pressed CD results: (click here to see the CD Speed graph)

Using Nero CD Speed 0.85e, confirmed the previous test results (Sequential I/O) that gave Toshiba SD-R1202 the third position. The average reading speed of the drive is 30.88x, which is higher than Yamaha's result.

The seek times of Toshiba drive are low and only Lite-On 16101B gave a better result in the "Random" and "1/3" seeking mode. In the "Full" seek test, Toshiba SD-R1202 leads with 195ms.

- CDR Media: (click here to see the CD Speed graph)

In the CD-R media reading test, the Toshiba drive gave a higher ending speed than in the pressed CD test, and as a reslt, the average reading speed is higher.

- HS-RW media: (Click here to see the CD Speed graph)

For the RW tests, we used Ricoh's HS-RW media. Toshiba read the HS-RW disc at 16.52x (average). The drive started reading at 9x and accelerated up to 22x by the end of the test disc.

- DVD Speed v0.52: (DVD Speed graphs for DVD-ROM, DVD-R, DVD-RW , DVD+R, DVD+RW)

The following tables show the DVD Speed reading results for Toshiba SD-R1202, for DVD-ROM media.

Toshiba SD-R1202 is a fast DVD-ROM reader and the seek time results can compete the most of the market DVD-ROM drives.

The drive kept the good performance in the DVD ripping and the DVD reading tests.

- Movie Tests

We tested the Toshiba SD-R1202 with many DVDs and our overall impression was very good. When playing DVD movies, the average CPU Usage was 45% using PowerDVD v3.0 Build 0421. We noticed no problems during DVD playback, and the quality of the picture was high, without any "mosaic" problems.
