Once again, LiteOn went with a MediaTek based DSP, the MT1828E. Below, you can see a scan of the double-sided PCB. Using a PCB with components on both sides slightly increases the cost and complexity of the unit, but also decreases the size of the drive. This is why most MediaTek burners have a smaller form factor.

On the front side of the mainboard, there is not a whole lot to see other than the Samsung 3.3V DRAM module. The reverse side of the main PCB can be seen below.

Coupled with the analog controller, the MT1616E, the SHOW-1633S provides all the features of NEC and Pioneer, as well as additional features like error feedback. All MediaTek controllers provide feedback to the PC on the number of C1/C2/C3 (or PI/PO) errors produced during a burn. Software like K-Probe allows the PC to record and graph these errors in the same manner that Q-Tools reports errors. This is a great feature if you are a hardware reviewer, but not something that we would recommend as a factor in a purchase decision.
Although we are accustomed to high pitch whines while writing discs, the LiteOn 1633S was extremely noisy.

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).
