The big difference between the iHOS104 and Lite-On's previous BD-ROM drives is that it reads DVD's at only 8x. In our tests, it started reading at 3.36x and reached a maximum transfer speed of 8.09x. 

CD Speed v4.7.7.16 - DVD-R and DVD-RW:

First, we'll look at the drive's DVD-R and DVD-RW reading performance. For this I made copies of our DVD-ROM test disk using some general use 16x DVD-R and 4x DVD-RW media from Verbatim and then ran our usual DVD read tests with CD Speed. The results are below.

The iHOS104 had no problems reading DVD-R, DVD-RW and DVD-R DL media. In all three cases, the drive reached a maximum transfer speed of about 8x.

CD Speed v4.7.7.16 - DVD+R and DVD+RW:

Next we'll look at the drive's DVD+R and DVD+RW reading performance. For this I made a copy of our DVD-ROM test disk using some 16x DVD+R and 4x DVD+RW media from Verbatim. I then ran our usual DVD read tests with CD Speed. The results are below.

Verbatim DVD+R DL
 

The iHOS104's performance was very similar to what we saw with DVD-R, DVD-RW and DVD-R DL media. Once again, the drive reached a maximum transfer speed of about 8x.

CD Speed v4.7.7.16 - DVD-Video:

For these tests I am using the US version of Transformers: The Movie on DVD. The disc is over 4GB and single sided.

The iHOS104 didn't slow down very much when reading single layer DVD videos. It started out at about 3.32x and reached a maximum read speed of 8.00x. Lite-On's new drive was also fairly quick when reading dual layer discs. By looking at the screenshot below, you can see that the drive's transfer speeds peaked at about 8x.

To see how well Lite-On's new drive worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: The Phantom Menace using the bundled version of PowerDVD. The iHOS104 had no problems playing back either movie and was fairly quiet.
