Are most CD-ROM/DVD-ROM drives ATA 33, 66, or 100?

Dumb question, I know, but I'm wanting to add a DVD drive and the IDE cable I have right now is stretched to the max. I need to get longer one, but I can't remember if an ATA 33 will be fine, or whether I need a higher one. BTW, the DVD drive I'm looking into is the Samsung 16x SD616 -- any opinions on it?

Thanks in advance,

Most drives (older ones - not new released) actually don't use Ultra ATA, they use either Multiword DMA - PIO MODE 4

the drives that do use Ultra ATA are almost Ultra ATA 33 - very few are ATA/66 and I don't think ANY are ATA/100

It would not even matter if it were higher than ATA/33 though. an ATA/33 cable would be fine!

I don't know anything about the DVD drive in question.. try here for more info 🙂
 
99 percent of all ide CDROM, DVD, and CDRW drives are either Pio mode 4 or ata 33. Pioneer or samsung made a ata 66 DVD drive but I dont think any performance was gained from the ata 66 since DVD drives dont get anywhere near 66 megs a sec. My 16x DVD is ata 33 and my 16x CDRW is Pio mode 4 and they both work fine. Where you do need ata 66 or 100 or 133 is with hard drives as they can theoritically use that 66 megs a sec and over. Most drives dont average over 45 megs a sec though making anything over ata 66 kind of rediculous.
