CD Speed v4.7.7.16 - BD-ROM:

To test the DX-4O1S's BD-ROM reading performance, I used the Blu-ray Disc version of The Fifth Element. This single layer disc is about 23GB in size.

The iHOS104 performed relatively well when reading BD-ROM discs. While not nearly as fast Lite-On's previous drives, it had no problems reaching a maximum transfer speed of 4.04x.

Lite-On's new BD-ROM drive had no problems playing back The Fifth Element and The Simpsons Movie using the bundled version of PowerDVD. Just keep in mind that if your monitor is connected to your video card using DVI or HDMI, both need to be HDCP compliant to play AACS protected titles. If not, you can still play them by switching the connection to VGA or using software like SlySoft's AnyDVD HD.

CD Speed v4.7.7.16 - BD-R and BD-RE:

Next we'll look at the drive's BD-R and BD-RE reading performance. For this I created a few data discs using BD-R and BD-RE media from Memorex and Sony and then ran our BD read tests with CD Speed.

Lite-On's new BD-ROM drive had no problems reading BD-R, BD-RE and BD-R DL media. In all three cases, the iHOS104 reached a maximum transfer speed of 4x.

Performance Revisited:

Like Lite-On's previous BD-ROM drives, the iHOS104 performed as expected throughout most of our tests. The drive had no problems playing back Blu-ray movies and read both single and dual layer BD media at 4x. It also had some fairly good seek times and was able to read DVD's at 8x and both data and audio CD's at speeds as high as 32x. With all things considered, the Lite-On iHOS104 gets a solid 8 out of 10 for the performance section of this review.
