Write Time/Quality Test - DVD+/-RW 4x Media

Though the DRU-720A is capable of writing +RW at 8x speeds and - RW at 6x speeds, we did not have any media on hand to test the drive. So, we used Ritek brand RW media rated at 4x to test the quality of the write. Take a look at our results.

Write Test - DVD+/-RW 4x Media

Disappointingly, the DRU-720A could only spin up to 1.98x speeds. It took 30:03 minutes to burn the full 4.38GB Ritek W04 DVD-RW media. Meanwhile, it wrote to the Ritek 004 DVD+RW at just above the full 4x speed that the media was capable of in 14:28 minutes.


Hold mouse over for the Ritek 004 DVD+RW image.

The Ritek W04 media has almost 3 times as many PI errors as the 004 DVD+RW media. The combination of the slow write speed and the amount of PI errors shows us that the DRU-720A, undoubtedly, had trouble writing to the Ritek DVD-RW media. Hopefully, a future firmware upgrade can fix this.

Screenshots of the 4x RW media read and write processes in Nero CD-DVD Speed as well as scans with PlexTools have been compressed into a downloadable zip file: 4xrw.zip

    that's why i want lightscribe, so i don't have to waste too much time. it can burn the label all day, i don't care, i'm away most of the time anyway and i almost never use the cd/dvd after i burn it.

    and "Take a art class or two and become more talented with a sharpie :)"
    would you say something similar to this to someone who wants a printer?

    #15: Our next roundup should include all of the highest speed media supported by the competing drives.

    #16: Sometimes. Although, there are brands of media out there that just do not work well with certain drives/firmwares.

    If you write at slower speeds are the errors less?

    Good review. Some more media scans would have been nice (and informative) though :)

    #2 - I was under the impression that all Sony drives are now made by LiteOn. At first it was just the cdrw drives but now the dvdrw are also.

    #3 - Take a art class or two and become more talented with a sharpie :) I used to make my own cdrw/dvdrw cases with custom inserts but after realizing how much time and ink I was waisting I finally went back to the sharpie route.

    My first couple of dvdrw drives were Sony and I had great luck with them but when I got a new black case I decided to get a new drive and the dvr-108 was on sale so I got that. I don't care for DL much yet and will not be interested until the price of the media gets to about 1/10 its price now.

    Is there a place that sells DL media for less than $7 yet? DL burner is a nice feature.. if you can use it and it's affordable. Personally, I still like my ND3500A with 2.18 modified FW. Burns TDK, Sony and Fuji DVD+/-R 8x media at 16x flawlessly. I'll need another burner soon so I'll be looking forward to Purav's next review.

    Keep up the good work guys!

    I would have liked to have seen the this up against the 8MB cache Plextor's. Are there plans for an optical shootout in the future.

    How about they test the 720 next to the old 710 with the latest firmware since it brings it up to the 720s specs.

    meant to say media are lagging behind as usual
