Curse you Emp! ;) I was going to be first here, but I was at the CDRlab.pl :D
Few weeks ago AOpen passed neccessary information to Nero, and we can see and test the results. You shown above a list of drives, for users not to common with pure h/w should know that AOpen 4410 is RICOH 5120 OEM. Below I'll present you with a few scans comparing the results among few AOpen drives, I currently have:
DVD1648/AAP f/w:1.05 (DVD-ROM)
DRW4410 f/w: 1.19 (DVD+R/RW, OEM RICOH 5120)
CRW5232 f/w: 1.03 (CD-RW)

We are scanning burned CD, 53m26s61f:




Although the CD-R is the same in all cases, the results are very different.

DVD-ROM DVD1648/AAP : The drive returns both, C1/C2 and Jitter. But it has the same bad point as LiteON DVD-ROM does. It can scan only with the highest speed, so the results should be considered as a 'real' result.

DVD+R/RW DRW4410: Only PI errors, no Beta, no PIF (PO), scan with the selected speed.

CD-RW CRW5232: Only C2 Error, no C1 no Jitter. Scan with the selected speed.

Now trying with DVD+R media.

Ok, two more scans, now trying Verbatim Pastel TY, media burned with LG GSA-4081B at 4x.



As we see 4410 does not report PO(PIF) and Beta. Althought the speed were set to Maximum it has no influence at the result since the media were scanned with 1.4x speed.

DVD-ROM, even when set to speed 8x (only slower was 5x) it works with maximum speed (ended with 15.76x). It returned information about Jitter, PI and PO (PIF).

I think we can find some time to test the new drives, even i feel the LiteON/Plextor combination will stay at our labs for quite sometime...

(in reply to SoBal)

Can you tell us what was the sampling interval / number of samples using the AOpen drives with the aforementioned scanning speed?

Also, what chipset does Ricoh/AOpen use (Ricoh's own)?

Thanks!

(in reply to emperor)

The CRW5232 result for C2 looks pretty useless - more or less flatlining at 80 average, on a burn that only shows moderate C1 errors on drives that report that.

I'd say it needs to come OFF the supported list!

(in reply to Halcyon)

Very interesting results. Is Plextools available to you for comparison? In my experience, C1/C2 values reported by Plextor drives are better indicators of disc quality. I run tests on audio CDs with CD players also.

(in reply to SoBal)

hopefully soon we will also run some tests...

(in reply to muchin)

Looking forward to your tests.

(in reply to emperor)

I finally looked at the graphs with my eyes open :)

Looks like the DVD-ROM is useless for c1/c2.

The result is too good to be true, esp. at that scanning speed.

Also, the dvd burner does not report PIF, which might be (according to rdgrimes) be a usable measure of disc readability (in the drive scanned).

And the CDRW burner is reporting perfectly silly figures :)

Unless Erik Deppe somehow pulls magic on these drives, I don't think they look very usable for scanning, imho.

It'd be really interesting to know the Chipset and the Scanning interval, if somebody knows those.
