BenQ DW1620
We took our first look at the BenQ 16X drive just a few weeks ago. Our second look at the DW1620 uses the same firmware, although we were able to get some better media.| BenQ DW1620 16x DVD-/+RW Drive | |

Our first test burns with the DW1620 made us a bit nervous. The drive seemed to jump quite a bit during the writing process and we didn't hesitate to contact BenQ about it. They, in turn, informed us of their "Write right technologies" and reassured us that this behavior was normal for the drive. Their "Write right technologies" are a combination of features including Walking Optimal Power Control II (WOPC II), which adjusts the power of the laser during the burning process to ensure a quality burn.
One cause of "errored" burns is a warped area on the surface of the disc. For a drive to optimally write to media, the laser must be at a 90 degree angle to the surface of the media, which is where BenQ's tilt control feature comes into play. By scanning the physical surface of the warped media and tilting the laser, the drive can both read and write to warped media where other drives would produce errors. The Block Error Rate Optimal Writing Control (BLER OPC) helps the burner perform better at the end of the disc, since that is where the most errors can occur due to warped media surfaces.
Another feature that is said to help the DW1620 read and write to media much more efficiently than other drives is its sliding cone, which helps support the media when clamped in the drive and provides for quicker and more efficient auto-centering of the media on the drive's turntable. Features like these are not advertised on most all of the other drives but they are still successful at reading and writing. We will see if these technologies actually help the DW1620 when we perform our benchmarks.

The DW1620 is based on the Philips Nexperia PNX7860E chipset, which works in conjunction with the TZA1047 analog processor to facilitate 16X DVD-/+R writing speeds as well as DVD+R DL writing capabilities.

I think some are forgeting that testing these things doesn't happen over night. Between other reviews, news, etc and normal working hours it could be quite easy to have a new firmware come out after you've already tested.For the plextor drive it does seem like bestbuy's website has them in stock for $140 with a $30 MIR. So is the extra's of a plextor worth the extra $30 to $40?

I notice with the Lite-On 1633 drive you was for the roundup still had the original firmware,there`s a new firmware "BSOK" update out dated 26th OCT that has "matched more media" support.I happen to own the external version and can say it`s very quiet while burning and also in playback mode,the only noisy thing is the tray when ejecting IMHO,btw I think it`s a great burner very low P1/PO errors and no bad burns so far.

What is interesting is I just bought a Plextor PX-716a at Best Buy this last week. It works GREAT so far. Will do more testing but so far it's fast and reliable. It is at UDMA 4 by the way. It flys.It came with both a White and Black face and door.

er, Nov 8 for PREORDERapparently they are still working out bugs
I note in the specs that the drive will run in UltraUDMA mode 4 or 66MB/sec in addition to PIO
Interesting

Can anybody comment on the noise level of any of these drives (esp. the NEC, BenQ and Pioneer)? I'd like to throw one of these in a sff and use it as a htpc, so a loud drive spinning sound would really bother me.KristopherKubicki - Monday, November 1, 2004 - link
Maverick215: Feel free to download the .zip files with all of the disc quality q-tools and nero tests.techfuzz: When we tested the drive 2.16 was the newest available.
As for the BenQ drive, we tested with the newest firmware possible.

From page 9 (Sony Review) <<...dual layer burners are pseudonymous with 16X burners...>>I think the word you're looking for is 'synonymous', not 'pseudonymous'. A pseudonym means 'a fake name', whereas a synonym means 'basically the same thing'. However, in Sony's case, pseudonym may be more accurate.

I find the average write speed of 11.88x for the NEC on 8x DVD±R MCC media very hard to believe. It would need to support them at max 16x speed to get this average speed and it does not, unless you've used a hacked firmware.I also doubt that the Pioneer is faster than the BenQ @12x on 8x MCC DVD+R if you compare the actual write time. Other tests have shown the BenQ to be a good 30 seconds faster than the Pioneer at 12x thanks to PCAV write tech (vs. ZCLV).
