Lite-On eSEU206 Portable 6x Blu-ray Disc Combo Drive

DVD Write and ReWrite Tests - Nero Burning Rom 9.4.26.0 and InstantBurn 5:

To test the DVD writing performance of Lite-On's new drive I used Verbatim 16x DVD+R, 16x DVD-R, 6x DVD-RW and 8x DVD+RW media. To get the writing times, a 4.38GB image was burned to our test discs using Nero.

The eSEU206 uses P-CAV, or Partial CAV, when writing to DVD+R and DVD-R media at 8x. By looking at the screenshots above, you can see that Lite-On's new drive starts writing at about 3.45x and accelerates, reaching its maximum speed at the 4GB mark.

The eSEU206 also features 8x DVD+RW and 6x DVD-RW writing speeds. In both cases, the drive uses Z-CLV to reach its maximum writing speed.

The eSEU206 performed as expected in our DVD writing tests. While not as fast as some of the internal Blu-ray drives we've looked at recently, it turned in some respectable times with DVD±R and DVD±RW media.

To check the media compatibility of the eSEU206, I ran a few tests using some of the media available in my area. The media types, along with the average time it took the drive to write our 4.38GB image, are listed below.

So what about writing quality? Using CD Speed we can test a disc's PI (Parity Inner), PIF (Parity Inner Fail) and Jitter rates. For these tests I used a Lite-On iHAS424 and read the discs at 8x with the PI and PIF ECC sums set to 8 and 1 respectively.

So what are "good" results supposed to look like? When testing with the iHAS424, the PI errors should not exceed 280 and the number of PIF errors should stay below 4. Since POF errors are uncorrectable, we really don't want to see any of them at all.

I also put these discs through a "stress test" by reading them back at 16x. By reading these discs back at this speed, we can see if there are any readability issues caused by the number of errors or high levels of jitter. 

The eSEU206's writing quality was pretty good with most of the DVD+R media we tested. Aside from a few small spikes, the PI/PIF rates stayed within acceptable limits.

Lastly, here are some results from our DVD-R test media. While the writing quality varied from one manufacturer to another, the results were fairly good for the most part.

To test the eSEU206's packet writing performance I used InstantBurn 5. Verbatim 6x DVD-RW, Verbatim 8x DVD+RW and Maxell 5x DVD-RAM media were used once again.

Double Layer DVD Write Tests - Nero Burning Rom 9.4.26.0:

To test the double layer DVD writing performance of the eSEU206, I used DVD+R DL media from Verbatim and RiDATA. I created about 8GB of random files and directories on my hard drive and then burned them to our test discs with Nero.

The eSEU206 performed as expected when writing to DVD+R DL media. In our tests, the drive took 27:47 to write 8001MB of data to Verbatim's 8x DVD+R DL discs. So what about writing quality? Take a look below.

The eSEU206's writing quality was pretty good with Verbatim's 8x DVD+R DL media. The PI/PIF rates stayed within acceptable limits and there weren't any readability problems. The results were also fairly good with RiDATA's 8x DVD+R DL media. However, there was a large PI/PIF spike where the writing speed dropped from 4x down to 2.4x.
