Well, a few surprises here. It seems that the new chipset needs some work in the media compatability area. Hopefully, this OEM drive will improve with the retail firmware updates.
the bad news is that TY seems to be one of the worst media for this drive. My first reaction was to RMA the drive, but with further testing, it seems this is a media issue.
Here's an audio disc burned at 24x on TY-48x media. The error curves are very similar at higher speeds, only with higher peaks.
Here's the same TY, data burned at 52x. The good news is that the drive will burn full speed all the way through.
Now here's the same disc as above, reading it in my 52246S drive:
Not looking too good is it?
Now lets try some RiTEK TG (TDK), rated at 48x, burned at 52x:
Here's the same media burned at 40x:
Next is some Maxell 40x, also RiTEK TG, burned at 52x:
Now some Sony48x, however the drive will not allow more than 40x burning on this media. It's identified as "Sony" in SmartBurn and MInfo. burned at 40x:
Last of the CDR's is Memorex Black 40x, also RiTEC TG, SmartBurn will allow 52x onthis media, but I know from past experience that 40x is better, so it's burned at 40x:
OK, time for some RW media. First is my trusty Verbatim US 24x, 650MB. the good news is that it will burn 650MB in about 3:41, which is a big improvement over the 52246S. Here's the bad news:
Reading the above disc in the 52246S drive:
Lastly, a TDK 10x (HS) RW disc, 650MB:
Hmmm, that's pretty damn good for HS RW media.
Clearly this drive is a disappointment in several ways, but it's hard to say it's a "bad drive" given the performance on the RiTEK media. RMA'ing this drive is tempting, but I think I'll play with it some more first. It has potential, especially in the RW area with the higher speed and P-CAV burning. It also burns faster at 52x than my 52246S does, and runs full speed all the way through the burn.
Tomorrow I'll flash with Qs04 and try some more tests.
