The AD-7240S was fairly quick when reading single layer DVD-ROM's. In our tests it started reading at 6.61x and reached a maximum transfer speed of 16.09x. Unfortunately, its seek times were not as low as some of the other drives.
Nero CD Speed v4.7.7.16 - DVD-R, DVD-RW and DVD-RAM:
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 disc using some general use 8x DVD-R and 6x DVD-RW media from Verbatim and then ran our usual DVD read tests with CD Speed. For the DVD-RAM tests, media from Maxell was used. The results are below.

Optiarc's new drive has a maximum transfer speed of 12x when reading DVD-RAM discs. By looking at the screenshot you can see that it starts reading at 5.90x and accelerates, reaching 12x at the 2.9GB mark.
Nero 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 disc using some 8x DVD+R and 8x DVD+RW media from Verbatim. I then ran our usual DVD read tests with CD Speed. The results are below.

The AD-7240S's performance with DVD+R and DVD+RW media was very similar to what we saw with DVD-R and DVD-RW media. The drive read DVD+R discs at 16x and DVD+RW media at 13x.

The AD-7240S didn't slow down very much when reading single layer DVD videos. It started out at about 6.54x and reached a maximum read speed of 15.94x. Optiarc'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 12x.
To see how well the AD-7240S worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: Revenge of the Sith using Nero Showtime. The drive had no problems playing back these movies with either program and was fairly quiet.
