Toshiba SD-M1612

The drive came in an OEM version. There is only one button on the front panel - Load/Eject. There is no even a headphones jack (maybe because the market is glutted with mainboards with integrated sound). The drive can read also DVD-RAM discs.

DVD-Video playback with the Cyberlink PowerDVD 2.55

The DVD-Video was played without any problems; no artifacts were noticed. During changing the layer the DVD quality didn't get worse.

Noise characteristics

At the maximum speed the drive makes quite a lot of noise. The reduction is possible only by means of exterior programs (CDBremse, Nero DriveSpeed). The speed, thus, can be 48x-32x-20x-8x. The Drive check program showed only 8x in the list of possible speed settings.

Vibration

When the drive worked with badly balanced CDs it didn't shine. The vibration was quite noticeable. But it didn't prevent the drive from successful reading of the disc at a high speed.

Thermal conditions

There are no any complains about its thermal conditions. The data were read after an intensive 2-hour operation:
T inside the case - 35°C
T of the upper surface - 41°C
T of the lower surface - 42°C
