Optiarc AD-7200S

For our CD transfer rate tests, we used the Nero CD-Speed utility and a set of data and audio CD-R/RW/ROM.

For each CDSpeed graph, you can click on the image to see the complete screenshot, including full measurements.

-CD-ROM

- US RW

The following CD Speed graph shows the reading performance with US-RW media. Reading reached a maximum of 32x, as per the specifications.

- AudioCD

In the CD Speed Advanced DAE quality test, the drive's average speed was 28.85X with a quality score of 98.1

- 90/99 mins Audio disc

90min audio

As you can see in the screenshot above, the drive read the disc successfully but it failed during the access times measurement.

99min Audio

The AD-7200S was unable to detect the 99 min. audio disc.

DVD Format

Now let's take a look at how the drive performs with DVD media. This time, a set of SL and DL DVD media was used. The drive is capable of reading at 16X maximum speed for single layer DVD ROM and at 12X for dual layer DVD ROM media.

DVD-ROM SL media -

PTP DVD-ROM -

The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, progressing towards its outer range.

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 we 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 part of the disc, so the drive starts reading from the outer tracks and progresses towards the inner part of the disc.
