i found some comments on another forum, which may be useful so i'll post here:
#1 : - The Samsung SH-S203B. This SATA offering is possibly the best drive on the market at present. It has speed, along with quality.
For : - Speed & quality of burns with CDRs, DVDs both SL & DL. Typically of MediaTek chip based drives, favours + media marginally. DVD-/+RWs is OK too. But not earth shattering.
Against : - Media support could be improved, bitsetting included in f/w as default. Scanning. N.B. With reg hacking this drive will scan, but lacks jitter reporting.(If sole drive then this scan along with TRT (TransferRateTest) should be adequate.
#2 : - LG GSA-H62N. This drive while quoting 18x max. Is only just a tad slower than the Samsung. So despite the 18x tag, this drive offers speed + quality (personally I feel the Samsung edges it here, on both counts).
For : - Speed & quality with DVDs, both SL & DL. This drive has a more definate preference for + media. Media support is quite good, but as with anything we always want more.
Against : - Quality of burns with DVDRWs & CDRs is below what you might expect from this quality of drive. Scanning in any form just not on. Again TRT can help, if only in a somewhat limited way.
#3 : - Pioneer DVR-212D. This drive while in some respects laggin behind the other two. Has one main thing going for it. Quality of burns not only with SL & RWs. But it's consistant performance with DL (ideal for backing up games). Put this in the frame.
For : - Versatility with much media (including budget) to burn to a good standard of quality. This applies to all formats whether DVD or CDR.
Against : - Somewhat a bit of a plodder when put alongside the above drives. Scanning also a bit unreliable too. Although the latest Pioneers will scan with limited & mixed results.
All of the above drives will not disappoint. Though one may suit your needs more than the others. SATA drives are definately the way ahead. In fact it probably won't be that far off before there isn't a choice.
Obmission!
The Plextor is left out. Simply becuase it is uncertain what support for these drives will be in the future. For they're still a drive to be reckoned with. If a tad expensive.
Lite-On. Only if scanning is of importance. Even this is forum related.
The Lite-On doesn't cope well with CDRs at all well. Struggles with DL (jitter, in fact slow it down enough & the latest gen drives struggle to do a simple Disc Quality scan with DL).
But is OK with SL as shown in many threads.
If possible get a Genuine BenQ for scanning (1620 < > 1650/1655).
If support (future) isn't that great a concern then Plextor makes #4.
If wishing to participate in forums scanning is of interest (failing being able to acquire a true BenQ) then the Lite-On makes #5.
i think i'll probably end up gettin the samsung, but someone else on that forum made a comment that it doesnt support "Jitter Scan"...which..i'm not exactly sure what that even is, or how important that might be. anyone happen to know?
