Nice review, but why aren’t the spikes mentioned? :frowning:

Nice review - thanks! :slight_smile: :clap:

The drive looks good so far.

Several of the DVD+R burns show PIF spikes at relinking points that are characteristic of NEC drives. I have had some serious problems with discs burned in my NEC 4551 when trying to read them in some other drives, notable two BenQ DW1655 drives and an old laptop drive, but also Read transfer slowdowns in two LiteOn drives.

Have you tried performing Read Transfer tests or other actual reading tests of some of those DVD+R discs that show PIF spikes in a BenQ DW1655/1650 drive or a LiteOn 5S/6S series drive?

Looking forward to also seeing some scans of CD-R media, because the NEC drives are some of the best DVD burners for burning CD-R media in my experience, so hopefully this is also the case with the Sony NEC Optiarc drives.

Was it a review instead of a preview before? :wink:

I read back the Sony 16x DVD+R media that was burned at 18x which had 7 relink PIF spikes.

However the media shows a PERFECT readback curve in BenQ 1655 and Lite-On 165P6S. :iagree:



Here, have a bunch of p’s: p p p p p p p p p p p p p p p :wink:

OK, that’s good! :slight_smile:

Excellent Preview and a very promising looking drive. By far the best quality burns i’ve seen at 18x burn speed, and fast burn times.

I want one of these drives. :slight_smile:

The law says that if you do get one, you must then Liggy+Dee-ify the fimware! :bigsmile:

Well, at least I think that’s what the law says, but IANAL. :stuck_out_tongue:

Looks like typical NEC drive. What does Sony have to do with these Optiarcs?

The Price, they jack up the price

Nice Jan70, thanks for the comprehensive review, when are you gonna take a look at the new Samsung drive?? I am waiting for your review before buying another burner.

@Liggy,

Can you already dump the firmware of these new 7170 and 7173 drives? I will get my 7173 one of these days and would like to have a bitsetting firmware for this drive.

I will post some CD-R tests soon. :flower:
