DVD+R DL writing quality
In the tests below, we will explore DVD+R DL writing speed and quality of Sony BWU-100A with widely available media from two manufacturers.

Quality test

Transfer rate test

High-quality Verbatim 2.4x DVD+R DL media made in Mitsubishi's Singapore facility never fails to burn well, even at speeds well above its certified 2.4x.
Sony BWU-100A produces a great burn, while also overspeeding this media to 4x.
Memorex 2.4x DVD+R DL

Quality test

Transfer rate test

This DVD+R DL media often presents a problem to other drives. Sony BWU-100A burns this media remarkably well at its 2.4x certified speed.
Summary
From our limited testing, Sony BWU-100A appears to be an excellent DVD+R DL writer, capable of very good burns with Verbatim and Ritek media.
DVD-R DL writing quality

Quality test

Transfer rate test

This disc has a problem at about 20% into the second layer. This result, while it appears to be of very low quality, is still readable, though at a reduced speed.
Summary
Given the very limited nature of the test, it difficult to draw conclusions. Sony BWU-100A created a readable burn with the generally difficult media type that we had available for the test.

except HDDVD perhaps



Unfortunately, 1x HD-DVD burners are just beginning to appear this summer [in notebooks], so HD-DVD burning has been no more than a theoretical possibility even though HD-DVD-R and -RW media has been out for months.
Toshiba's SD-H903A 1x HD-DVD burner is awfully late for a product launched/unveiled six months ago. They better hurry. You know: train... leaving the station...





Just wondering if that benQ you used for scanning is a rebadged liteon? If it's genuine benQ, I wonder why you didn't use cdspeed for scanning + jitter, it would be nice to see how good the jitter was on some of those discs that had ridiculously low error levels (MCC003 in particular)



DW1680 is a MediaTek/Lite-On design [otherwise KProbe wouldn't have worked with it], equivalent to LH-16A1P.
We use KProbe for quality testing to keep reviews consistent, but you are right, CD-DVD Speed does provide more quality data.
In BWU-100A DVD+R burns, jitter is pretty low. It usually averages 9% +-0.4% when measured by either BenQ or Lite-On drives.




I believe this is the way CD-DVD Speed reports capacities.
25,025,xxx,xxx bytes is the so-called 'gross' BD-RE capacity before 12,288 clusters are allocated for the inner spare area (ISA0).
The same number of 64 KB clusters is lost with BD-R as well, but the 24,220,xxx,xxx number reported for BD-R is the 'net' capacity.
In both cases, usable space ends up being the same 24,220,xxx,xxx bytes.


Havent payed much attention yet as its still sorta early to consider using anything newer than DVD as a cost effective measure..
But yeah, absolutely too small for next gen, which is sad because I hate sony and everything they are about.
btw nice writeup 009


thanks for the review, I appreciate it, I was wondering if anybody here, maybe able to help me with a question, I am thinking of fitting one of these into a custom HTPC case. Is this the same same size dimensions as current DVD drives and also, does the front bezel remove easily as current drives, I need to remove to be able to fit the drive into my custom case, as long as it is standard sizeand the bezel comes off, I will be fine.
thanks for any feedback.


Yes, the bezel is removable. It is held in place by plastic tabs, as with any other drive.
BWU-100A is a standard 5.25 inch drive that is 190 mm long. This is longer than usual and about the maximum length that 5.25 inch bays are designed for. It may be a tight fit in very small cases like Shuttle. I don't think you will have trouble fitting it in an HTPC case, but to be sure, measure the length of the drive bay.




...is this true? BD-R at 1x? Is this only on the OEM version? I am also looking at a (retail) version from ebay and wondering if anyone else had same experiences... thx
