Personally only advantage of scsi is lower cpu useage but with ultradma enabled an ide device isnt too bad (vs pio mode 4).
frankly i havent heard of scsi ones for less than a fortune?
and i have used/installed ohh a couple hundred ide ones
very few problems. i spent 88$ got an 8x i/o magic dvd
Actually, the only SCSI DVD-ROM I've seen locally is Pioneer DVD 10x/40x. There are probably many more available in my area (Vancouver of Canada), but I'm probably just not keeping my eyes peeled. You might want to try CNet for some reviews.
The IDE vs SCSI question has bugged me for a long time and I have long thought that my SCSI drive is far superior to any IDE drive. Turns out that the real reason my SCSI HD is so much faster is because it is 10,000 rpm not because it is SCSI. DMA brings IDE up to very near SCSI performance on a single computer. SCSI only really begins to shine in a multiple drive or server application. SCSI allows longer cable lengths so most external drives are SCSI. SCSI is the only choice for a server but IDE with DMA is a much better choice for a personal system. SCSI DVD is hard to find and expensive. A Pioneer 16/40 IDE drive from www.goroyalpc.com is only $81.00. Actually I wish you would buy a SCSI DVD so we could compare speeds and answer the question with no room for doubt.
There is another reason to consider a SCSI DVD/CD-ROM.
In my case I have a ATA100 hard drive, an IDE Zip drive, and a CD-RW IDE right now for my new system I am putting together. I also need to purchase a new DVD drive.
Right now I have the ATA100 hd on it's own channel, so that it can get the full use of ATA100. I have the CD-RW and Zip drive sharing the other channel, since neither is ULTRADMA. If I bought an IDE DVD drive, the best I can find is ATA-33, which I would have put on the same channel as my hard drive. If I did that, I would restrict my hd to ATA-33, which I don't want to do.
However, if I go with a SCSI DVD or CD-ROM drive, I can keep the hard drive on it's own channel and not have to worry about restricting it.
Does any of that make sense? I'm just starting to get a grip on it myself!
Maybe so, but I also have a SCSI scanner as well. Problem is my old system used an ISA SCSI card, which I can't use in a new system. Thus I will be getting a SCSI card (or more likely a K7 Master-s motherboard with integrated SCSI) anyway. If the SCSI DVD drives perform as well as the IDE ones, I may as well get the SCSI one. I think it's a Pioneer model 305S, 16X/40X.
