I'm guessing the OEM version of the drive will be available about the same time.

thanks.
so only 5x DVD-RAM.
wasn't this the drive that was supposed to do 16x DVD-RAM ?

so what's so new and special about this drive?
why the jump from 3xxx to 4xxx ?

As far as I know, the 16x DVD-RAM was just speculation due to the drive's chipset.

I think the jump is due to it being a Super Multi drive.

I wonder if it's a LiteON OEM or using the MTK chipset? :o

It's also possible that it's an NEC design, but manufactured by LiteON..... or it might be 100% NEC. Only time will tell I suppose.

I was poking around the FCC's website and it looks like this drive was originally going to be called the ND-3550A. NEC filed with them back in July and then again in August stating the name change.

July filing

August filing

If you look at the schematics (pdf), you can see that it uses NEC's μPD63645 and μPC3345 chips. Oddly enough, the manual makes no mention of DVD-RAM support.

Hello!

I´m not very impressed about the writing-quality @16x. Overall to high PIF, 8x could be better, too.
