Optiarc AD 7260S review

2. CD, DVD reading

For our CD/DVD transfer rate tests we used the Nero DiscSpeed utility and a set of data and audio CD/DVD R/RW/ROM media. Here we test the maximum reading speed of the Optiarc drive for each type of disc. For comparison, we have included the corresponding reading results two other 24x DVD burners, the LiteOn iHAS524 and the the Optiarc AD-7240S.

-CD-ROM

The following CD Speed graph shows the reading performance with US-RW media.

- AudioCD

In the CD Speed Advanced DAE quality test, the drive's average speed was 28.50X with a quality score of 100.

A typical audio ripping task finished at an average reading speed of 28.7X:

- 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.

 

LiteOn iHAS524 Optiarc AD-7240S Optiarc AD-7260S
Average Speed 8.65x 8.85x 8.90x
Random seek 118ms 130ms 148ms

 

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.

DVD Ripping speed -

Ripping of a single layer DVD movie:

  LiteOn iHAS524 Optiarc AD-7240S Optiarc AD-7260S
Average 5.766KB/s KB/s (4.2x) 11.761KB/s (8,5x) 11.742KB/s (8,5x)
Maximum 16.741 KB/s (12.1x) 16.451KB/s (11.9x) 16.667 KB/s (12x)

Summary

The reading process of almost all media was completed without read errors and at speeds that match the drive's specifications. It is obvious that the CD and DVD reading capabilities of the AD-7260S and the AD-7240S drives are the same.
