I-O DATA BRD-AM2B/U Blu-ray Disc Writer

Nero CD Speed v4.53 - DVD-ROM:

A little editorial note here. Like a CD-ROM, you will get different benchmark results depending on what kind of discs you are using. You are probably going to get varying results from a full data disc to a single layer movie disc. You're also going to get different results for single and dual layer discs.

The DVD Speed website recommends using a single layer DVD-ROM disc with a capacity of at least 4GB. If you use a dual layer disc you probably won't get the best results because most DVD-ROM drives slow down to read them. Some even slow down to read single layer DVD-Video discs. To make a long story short, I am using a 4.37GB single layer, single sided disc for this test.

The I-O DATA performed as expected when reading single layer DVD-ROM's. In our tests it started reading at 3.41x and reached a maximum transfer speed of about 8.23x. While this wasn't enough to top the drive from Pioneer, the BRD-AM2B/U's seek times were a bit faster.

Nero CD Speed v4.53 - 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 4x DVD-R and 2x DVD-RW media from Verbatim and then ran our usual DVD read tests with CD Speed. The results are below.

I-O DATA's new drive had no problems reading DVD-R, DVD-RW and DVD-R DL media. In all three cases, the BRD-AM2B/U reached a maximum transfer speed of about 8.2x.

Maxell 5x DVD-RAM

The BRD-AM2B/U has a maximum transfer speed of 5x when reading DVD-RAM discs. By looking at the screenshot, you can see that it reads at this speed from start to finish. Unfortunately, the drive's seek times were also very high.

Nero CD Speed v4.53 - 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 4x DVD+R and 2.4x 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 BRD-AM2B/U's performance with DVD+R, DVD+RW and DVD+R DL media 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 8.2x.
