Does anyone use a scsi cdrw on their cyberstorm scsi controller?
Im asking because Id like to know whether a '060 or PPC would be able to use an ultra scsi cdrw drive, im asking because the one im looking at requires at least a Pentium II @ 300mhz or G3 @ 300mhz.

That spec will be for maximum write speed no doubt.. You will easily be able to burn at a slower speed..
scsi hd to scsi burner will be the quickest path.

The CDRWs are probably limited to narrow SCSI, so depending on your SCSI adapter you can get up to 10 MB/s throughput - may just be enough for 32x speed. The burner itself does not care about your CPU at all, it's the software that depends on it.

The CDRW burner may not care which CPU is in the computer it is installed into, but correct me if I am wrong, the speed at which the data can be processed and burned to the disc certainly is dependent on the speed of the CPU. If it were not, then a SCSI CDRW connected to my A500 w/7mHz 68000 could write CDs just as fast as my A4000 w/50mHz 68060.
Since the question was about a CyberStorm, perhaps Zac67 was meaning that it did not matter which CPU the CyberStorm had, the 68040 or 68060. In other words, the software will run faster on a faster CPU.

68000 A500 with SCSI CDRW connected is able to burn CDs just fine, if you burn from image file and the source HDD and the SCSI interface is fast enough.
The burning process only gets CPU bound if the CD is burnt on the fly, without image file.

The Win/MacOS/whatever software bundled with the drive needs the 300MHz, not the drive itself.
I had a Plextor PX-W4012TS in my A4k/CSPPC, worked fine.
Oh, and I also had an LG GSA-4163B on the internal IDE controller for a while. I seem to vaguely remember burning a couple of CDs with it, albeit slowly.
On the back of the box it says "Minimum Requirements: CPU P4@2.4GHz or Higher - RAM 512MB or Larger recommended - HD space 10GB or more - Direct X 9.0 or Higher - Videocard Memory 128MB or Higher recommended". Of these I had only the HD space, so I learnt two things from this revelatory box:
#1: My CSPPC@233MHz/50MHz could use the drive, ergo it must be able to meet the "Minimum Requirements", and therefore it must be at least as fast as a P4@2.4GHz :-o ;-)
#2: "Higher" and "Larger" should always be written with capital first letter. (I have no idea why. Thus were The Words written on The Box.) :-P

SCSI devices DON'T NEED INTENSIVE CPU LOADS!
Like Piru said, ONLY if you try to burn ON-THE-FLY archives you will get in problem.
SCSI controllers handles the data in the SCSI chain by itself. So if you generate an ISO image FIRST AND burn it in speeds lower than 32x, you don't get a single problem with it.
Please don't compare the lightweight and elegance of Amiga's OS with the ignorance and brute force of those crappy M$ winblows.
Only the supplied software who comes with the device itself need that stupid configuration to work.
I am clear enough?
Sorry if those words offends you, in any way.

Are you yelling at me here? :-? If you are, I would like you to take a closer look at those pictures of little faces I placed right after the words "as fast as a P4@2.4GHz". See how the yellow one winks at you? That was supposed to tell you something about the previous sentence.
Furthermore, I would have to be immensely stupid to claim something like that based on a clearly senseless chain of deduction. "A CDRW works, so 50>2400"? Oh, come on now. I might be [d]a bit daft[/d] delightfully eccentric, but that's just too much.
Apparently my wording was too complex. Perhaps this (http://en.wikipedia.org/wiki/Irony) might help to understand what my intentions were.
