LITEON iHAS422 22x

2. CD/DVD reading tests

For our CD transfer rate tests, we used the Nero Disc Speed utility and a set of data and audio CD-R/RW/ROM. The drive can read CD media at a maximum speed of 48X.

For each CDSpeed graph, you can click on the image to see the complete screenshot, including full measurements. For comparison, we have also added the corresponding results of another 22x DVD burner, the Samsung SH-S223F.


Average Speed
LiteOn iHAS422 36.94X
Samsung SH-S223F 37.15X


The following CD Speed graph shows the reading performance with US-RW media. Reading reached a maximum of 40x, as per the specifications.

- AudioCD

In the CD Speed Advanced DAE quality test, the drive's average speed was 33.13X with a quality score of 100.

A typical DAE task with an 80min non-protected Audio CD produced 32.2X average ripping speed.

99min audio

The drive was not able to burn the 99min 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 -



Average Speed
LiteOn iHAS422 6.16X
Samsung SH-S223F 12.13X


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.

Average Speed
LiteOn iHAS422 9.15X
Samsung SH-S223F 9.09X


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.
