What is the major diff between an IDE DVD-RW and a SATA DVD-RW besides the fact that one is SATA and one is IDE. Do you really see a preformance increase in a SATA DVD-RW over an IDE DVD-RW?
Well I learn something new every day. Hadn't realised SATA optic drives had been released but it seems there are a few on the market. Since SATA operates on ATA150 and IDE on no more than ATA100 there is a theoretical difference in performance between the two types of drive. In practical terms I doubt there would be a "Visible" detectable difference when it comes to recording. It is probably easier to instal a SATA drive than IDE as there are no jumpers to worry about and the SATA cable is certainly tidier than the old grey ribon.

There is no difference in performance. No optical drive can come close to maxing the bandwidth in an ATA100 connection.

I noticed the plextor SATA 16X DVD-RW Dual layer is 120 bucks vs the same one that is IDE that is only 85 bucks. So you have to shell out 35 more dollars for an SATA that you will not be able to tell hardly any diff???? Doesn't make much sense.
I have also seen an Aopen SATA CD-Rom/DVD-Rom combo drive that ran for 55 dollars.
I just don't see the point in spending an extra 35 or 40 bucks to not notice any real preformancs differances.
The only reason I could see having an SATA DVD-Rom as of now is if you have an IDE Hard Drive and you only have one ATA connector and you don't want both devices to be on the same IDE cable.

oops, a couple of bad clicks and see what happens......
i have no comments to make on this topic.
thank you.:looks embarrased then walks away:

I didn't realize that SATA optical drives were on the market yet either.
Correct me if I'm wrong, but don't IDE optical drives only run at ATA33?

I think the issue here is how much data can be read/written by the lasers in these drives. I think that IF the ATA33 transfer rate had become a bottleneck the drive controllers would have simply been redisigned to run at 66 or higher. SATA drives are simply a marketing ploy IMO. I'm not up to speed on how the optical drive is seen by the BIOS, which seems to be the reason we haven't seen these drives before.

Michael J is right. There isn't any diff. in performance.
To get the data transfer bandwidth you should multiply the 'x' factor by 1385 KB/s, so a 16x unit bandwidth is: 16x 1385 = 22160 KB/s or 21.64 MB/s, they cannot saturate the ATA33 bus even if this speed was achievable, but this is only true in the most inner part of the disk, the average speed is even low, so ATA33 interface is fine.Hope this helps.
