DIGISTOR DIG-79102 Portable 6x Blu-ray Disc Writer

Nero CD Speed v4.7.7.16 - DVD-ROM:

For this test I used a single layer, single sided data DVD-ROM disc that is 4.37GB in size.

 

The DIG-79102 performed pretty well when reading single layer DVD-ROM's. In our tests it started reading at 3.40x and reached a maximum transfer speed of about 8.20x. Unfortunately, like in our CD read tests, the drive's access times were a bit high.

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.

The DIG-79102 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.

DIGISTOR's new drive has a maximum transfer speed of 5x when reading DVD-RAM discs. By looking at the screenshot you can see that it starts reading at 3x and then accelerates, reaching 5x at about the 1.5GB mark.

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 DIG-79102'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.

Nero 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.

 

	Transfer Speed			Access Times			CPU Usage
	Average	Start	End	Random	1/3	Full	1x	2x	4x
DIGISTOR DIG-79102	3.03x	1.68x	4.06x	183ms	203ms	360ms	7%	12%	24%

The DIG-79102 wasn't nearly as fast when reading DVD videos. In our tests, it reached a maximum speed of only 4x when reading both single and dual layer discs.

To see how well the DIG-79102 worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: Revenge of the Sith using the bundled version of TotalMedia Theatre 5. The drive had no problems playing back these movies and was fairly quiet.
