Fall 2004 DVDR Roundup: Dual Layer and 16X DVD+R

Write Tests (cont'd)
The DVR-108D, ND-3500A, and the GSA-4160B couldn't make it to the 8x mark as did most of the other drives. Though Ritek is one of the higher quality media like MCC, those drives still had some trouble working at the media's rated write speeds. The DDW-163 performed the best with the R03 media at 10.20X speeds while BenQ's DW1620 could not write to the disc at all.
Sony's DRU-710A and BenQ's DW1620 were the only drives capable of writing to MCC 004 media at 16x speeds using the CAV write method. All other drives were either not capable of handling this media at the full 16x speed or choked on it from the beginning. The GSA-4160B made it to 14X but couldn't hold it until the end of the write and the 108D topped out at 12X with its Z-CLV method of writing.
With the 16x Ritek media Nu Tech's DDW-163 was the only drive that would cooperate and push the speeds to 16x. All other drives either burned the 16x media at 4X or could not write to it at all. Ritek is not the largest MID available, but we were a little surprised to see so few burners actually capable of proper write descriptors. New firmware revisions will fix this issue in our other burners, but for the time being we were slightly dissapointed.
The only drives that burned coasters with dual layer media were Sony's DRU-710A and MSI's DR16-B. The rest all burned the dual layer media at around 2.4X while the DVR-108D and ND-3500A burned at about 4X speeds.

Just want to add an info about BenQ DW1620 pricing. I bought DW1600 3 days ago at SG$ 98 (that's about US$54-58). After upgrading the BIOS, it's now on DW1620's firmware B7M9. If the physical is the same as DW1620, it's effectively the cheapest 16x among the rest.kernelgui - Monday, November 1, 2004 - link
On page 13 where you published the test results with Ritek G05 media the graph heading indicates DVD-R 8X write speeds, however the smaller print below that indicates DVD+R media. Can you perhaps clarify if this table is based on + or -Thanks,

Thanks for the great review! Just one note of possible mistake - you have the DL R speed of the ND 3500a @ 2.4 when I believe it should be 4x.KristopherKubicki - Monday, November 1, 2004 - link
Maverick215: Testing 8 DVD drives takes more than just a few days. Our roundup was submitted Mid October and posted Nov 1.The zip files are at the bottom of each drive page. Look at the bottom of page 6 for the Benq.

KristopherKubicki: Let me see if I got this.You say that you tested the most recent firmware available on the Benq. Your previous review was posted September 29th, 2004. The next firmware released was B7K9, files in that zip are dated 9.27.04 and it was posted to benq's US site 9.29.04 (the same day the initial review was released) So if you "... tested with the newest firmware possible" then either http://images.anandtech.com/reviews/storage/16xosd...
is outdated or you tested the drive for 'this' roundup 'before' the previous review was released. I'm inclined to think the latter is true based on the features of B7K9. Similarly, "(your) second look at the DW1620 uses the same firmware, although (you) were able to get some better media." I assume you got this media prior to 9.29.04 as well...

Just trying to figure this out for myself here (btw I can't seem to find the .zip files you refer to). I have no vested interest in any of this, just like to see things clearly.

Back to the firmware issue. B7K9 introduced a great many write strategies changes.
I will pick out the media tested that seems to have changed since before B7K9
Mitsubishi (MCC 03 RG20) DVD-R is now 16x (should put speed about the same as NEC)
Mitsubishi (MCC 003) DVD+R is now 12x (should be about the same as the RITEK test on the BENQ)
Ritek (RITEK R04) DVD+R is a 16x supported media
Mitsubishi (MCC 004) possibly had a write strategy change (uncertain) to make it full 16x; same for (RITEK R03)

Don't get me wrong I understand you guys can't test the latested of the latest ultra alpha zeta laser tool chain master firmware (yes I made that up as I went) and compile a review/comparison instantly. But I would expect if you are using new material for a new review that you use the latest firmware/software etc that is available at the start of that review/comparison. At the VERY least you could mention that firmware revisions/updates/etc have been made (google is easy to use) and likely improve the results of XYZ. Further mentioning new features have been introduced, such as in B7M9 (released 10.27.04) where high speed (8x) disc quality testing with nero cd/dvd speed has been added (must use latest firmware, with latest software).
I may not expect to see such things on (insert company fanboy website here) but I certainly expect nothing less than what I suggest from "the leading IT source for hardware analysis and industry news"

BTW CDfreaks says the 1.01 firmware is out.Bozo Galora - Monday, November 1, 2004 - link
Actually if you look at store pickup it shows in stock (for me) at several places. But no one at those friggin stores ever answers the phone.Going out there right now to see, pick up 3 if they have them.
Thanks for heads up.

The Modesto, Calif Best Buy had 5-6 the night I got mine. I was shocked to see it there. I am glad I bought it. My friend has the 712 and never a coaster after at least 500-600 DVD's and hunderds of CDR's. And the DVD's play on anything in my house including a Sony DVD that hates all burned media.Same with the 716a so far.

We will test a PX-716A as soon as we get a sample.Kristopher

Nm they are backordered till the 11th - 17th. I'll have to check my local BB's to see if any of them got it in.
