Nero CD Speed v4.7.7.16 - BD-ROM:

To test the BWU-300S'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 BWU-300S performed very well when reading BD-ROM discs. In our tests, the drive started reading at 4.14x and reached a maximum transfer speed of 7.99x.

Sony's Blu-ray Disc writer 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.

Nero 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 single layer BD-R and BD-RE media from Panasonic and Memorex and then ran our BD read tests with CD Speed.

Sony's new drive had no problems reading BD-R, BD-RE and BD-R DL media. In our tests, the BWU-300S was able to read both BD-R and BD-R DL media at about 8x and BD-RE discs at 2x.

I should point out that the BWU-300S will not read all BD-R and BD-R DL media at these speeds. If you want to read discs at 8x, you will need to use media that is capable of writing at this speed. If not, BWU-300S will limit the read speed is to the disc's maximum writing speed.
