Hi to all who reside here! (or lurk) :o) I have been following this thread since it started and could see there were several knowledgable responses to the original question. I thought adding a little of my experiences to the discussion might help also. SCSI and Unix/Linux have always been best friends and if budget would allow, should be anyone's choice when building/buying a system. It is just better all around, plus for a true multitasking OS such as Linux, it's the best answer. Since moving from the Amiga computer/w scsi to Linux on a very fast PC system/w IDE, I have had several opportunities to make comparisons. Now realize, that the Amiga is only a 060/50mhz cpu, while the Linux machine is an AthlonXP 1700+ setup! I mention this point because some have made reference to the cpu playing a big part in the speed differences. I don't think this is the case. Multitasking is much more easily accomplished on the Amiga with scsi versus the PC with IDE. CDRW write times, with very nearly equal drive specs, are easily one half to one quarter the time on the Amiga compared to the IDE! Loading programs, reading, writing on the scsi is considerably faster on a 4gb drive than the 13gb IDE drive in the PC. Bottom line is that IDE is cheaper, slower version of scsi and will never give you the advantages of scsi. Plus, one has to add in the still older and clunkier design of the PC hardware versus the more updated design of the Amiga and scsi. Just some observations, your mileage may vary. My point is if budget will allow and you need or want the added capabilities of scsi, then get it, you won't want to go back to IDE again!

Some times ago, I used a little program to measure the speed of a cdrom. Asus 50x EIDE = 24/25x when I was lucky. Once it reached only 8x, because CPU had something better to do. Plextor 40X SCSI = 41,5x was ALWAYS my best... The performance was always the same.
The issue is more than just SCSI vs. IDE; it's Asus vs. Plextor, and Plextor is almost guaranteed to make better CDR(W) / ROM drives.
Not completely. Asus is one of the best CD-ROM EIDE unit I have seen around. And my tests were done with the same CD, always: why should the cdrom be faster or slower on a CD, if not because of the CPU getting stressed?
That's why I have a Plextor 12/10/32S CDRW drive, with which I am extremely satisfied (25X-30X ripping w/ Linux 2.4.16). I went for SCSI over IDE because I doubt my machine (233 Pentium I MMX w/ 32MB of RAM) could handle the load on its IDE bus during burning at 12X.
Yes you are right.... I got a friend of mine with an 8x Cd-rw and he can only go at 4x without risking uverruns...
