Read Tests

Like manufacturer-specified write speeds, specified read speeds are not always the best measure of a drive's performance. We have chosen select media to test the following drive read benchmarks.

CD Seek Time
For our CD seek time test, we used a CD-ROM filled with 700MB of data.

The DRU-720A had seek times much higher than the 710A and even the 540A, which had the lowest seek times. We found the trend to be a bit odd, since we're used to drives improving as newer models are released.

Take a look at how the DRU-720A performs with DVD media.

DVD Seek Time
For our DVD seek time test, we used a 4.5GB DVD-ROM with the maximum 4.35GB of data.

Though not as quick as the DRU-710A, the 720A had a random seek time of 105ms, only 2ms faster than the DRU-540A.

4.5GB DVD Read Speed
For our 4.5 DVD read speed test, we used a home made 4.5GB DVD-Video disc.


9GB DVD Read Speed
For our 9GB DVD read speed test, we used a pressed dual layer DVD-Video disc, specifically "The Matrix".


With the 4.5GB home-made DVD-Video, the DRU-720A had read the disk the fastest at 6.17x. It's not as quick as some of the other 16x drives out there, like NEC's ND-3500A or Pioneer's DVR-108D, but it is an improvement over the older Sony drives.

As for the read test with "The Matrix", the DRU-720A doesn't perform as well as its predecessors. The DRU-540A reads the disk faster than the 720A and 710A at 6.91x, while the 720A comes in at 4.3x.

    "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."
    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!

    bofkentucky: we have a second 16x roundup in the next few weeks.

    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
