Thank you, IWO!

As I wrote some posts earlier my 1640 works fine with Prolific 3705 chipset enclosure. It is also compatible with Oxford 911 chip, however with the latter you can't reach x16 burns. Epass chipset wasn't good for my 1640 and I don't know how new Oxford 922 (firewire 800) works.
I don't know if anybody succeeded in connecting BenQ via adapter cable.

Do you have the Oxford 911 or 911+ ?

question time

does it have to be a specific version or will any prolific chipset do?

like these

also will be flashed to BEGB

No, I don't, but I know a guy that has one that works with BenQ 1640.

I am saying that they changed the chipset on the USB only enclosure and may well do so on the firewire/USB version as well. Dealsonic was very precise in identifying the chipset and Plumax is considerate enough to change the part number when they replaced the chip so I wouldn't worry if you make clear to Dealsonic what you want.

Is this true for other, non-BenQ solutions?

It really depends on the chip/drive comination. I have an ALI chipset which is 12X on one drive and 16X on another.

BTW, I would never burn anything at 16X anyway. The quality is much better at 12X, the disc longevity is better, and the time is only slightly longer with 12X.

Many members reported Prolific PL-3507 works fine, and you need to connect the drive via Firewire for maximum write and read speed (16x). You may also want to check this thread.

You should be able to get 16X on the USB2 side of a 3507 if you flash the 1640 to the external firmware. I have no problem reaching 16X this way.

I typically only BURN at 12x, but I rip at 16x all the time!!!!

Where is your data for this assertion? It's a (remote) possibility that a 12X burn might have increased longevity but this certainly has not been proven.

which enclosure has the 3507 version?

More or less the same question you asked 2 days ago.

Don't take me wrong El_Mariachi_X, but it is required to do a SERCH before posting and if you look around this topic has been brought up quite many times lately.

BTW, we have at least three parallel threads running about the same question; enclosure for 1640.
Somebody...

About 2 years ago, I read a presentation from a top tech guy at a company dealing with a long term test to determine media lifespan. One of the things he did state without reservation, was that faster burning speeds resulted in shorter media life. He never said how much, but I believe what he said as he has no bias towards a particular media company and he was responsible for exactly the information he was discussing.

Some people say they will wait and see as they don't believe this. Some people also still believe the earth is flat as well. I prefer to believe an expert in the field and hope the results of these tests come in soon.

This is what you want; nothing else.

What a load of BS. "About 2 years ago, I read a presentation..." blah, blah, blah.
Your analogy equating the flat earth theory with how DVD recording speeds relate to disc longevity is without merit. There is empirical data that the earth is a spheroid body. There is no data that a DVD recorded at 12X will outlast one burned at 16X.

Hey you don’t have to get so aggravated, you have the right to challenge Chas statement but we don't have to be rude and harsh. Chase is experienced member of this forum and his contribution is well taken.

[zevia]

Okay guys, please keep it friendly. That's not the way we treat other members on this forum.

PS: I am merging three threads with the same topic so that we can focus better. Thanks pinto2 for your suggestion.

No wonder I was having trouble figuring out how my posts got here. Thanks for the heads up.

The PL-2507 will not work with the BENQ DW-1640 as it has the same verify and read issues as the PL-3507 before Prolific released the firmware upgrade. I am not sure the PL-2507 is able to be upgraded by firmware. Prolific has not responded to questions about this.
