80 wire IDE cable for CD/DVD drives?

[Pez D Spencer]

An 80 wire IDE cable isn't required for CD/DVD drives are they? If I remember right CD/DVD drives only run at ATA33 or ATA66 speeds (I cant remember which), and only hard drives running at ATA100/ATA133 speeds need an 80 wire IDE cable right?

I don't have an exrta 80 wire IDE cable right now so I am using a 40 wire with my 16x CD-RW/DVD-ROM combo drive.

Im sure I could dig on Google for a minute and find an answer but I dont really feel like it.

Thanks for helping me out on this.

they require 80 pin.

uhh.. a 16x cdrw/dvd drive is probably only ata33.

Yeah. DVD read speed at 1x is 1,385,000 bytes per second. 16 x 1,385,000 = 22,160,000. Max the thing out, and it won't get to 33MB/sec.
80 wire cable won't hurt, but it's hardly necessary.

I has to switch to a ATA33 cable for my NEC burner when one of ATA100 cables stopped working. I haven't noticed any difference at all in reading or writing speeds.

yes the 80 is needed for DVD burners my plextor 716 needs it to run UDMA 4

yes, but he has a cd-rw/DVD-ROM drive...

shouldnt be needed for that drive, but again, it wouldnt hurt

Its not required for any type of -Rom drive, some dvd burners can benifit from an 80 pin cable but it still not really necesary.

Not all require 80 wire but they can all benefit due to reduced cross-talk. Bottom line is there is no reason to use 40.

To use Ultra DMA modes over 2, a special, 80-conductor IDE cable is required.

*Edit: Means ATA66 and up needs 80-conductor cable

40-wire will limit operation of that channel to 33MB/sec. If your drive is capable of 66MB/sec and up, 80-wire is the ticket. At one time I heard that some mobos were sensitive to different cables on the two IDE channels. Since that time I have used 80-wire cables the great percentage of the time even though precious few PATA optical drives can actually tax the data rate limit of a 40-wire.
