I do not know your experiences with the SCSI systems, but we here did not had very luckly, so I have no comparasion for that.
What I can say is we can achive to play with NO frame loss 30fps in our case, up to at least....

1 mov with 2400 x 800 PhotoJpeg 75%
or
1 mov with 1024 x 768 PhotoJpeg Uncompressed

2 mov with 1024 x 768 PhotoJpeg 75%

4 DV movs from the original Cat Library.

I am conservative in that, and of course depends a lot of the movie, and other factors. I do not know what you can achive with the SCSI, but for us here is doing the job, and is cheapper and easier to work than the SCSIs.

ah but you see gian - you can only play back 4 dv movies from your raid- that is pretty typical.
and not very good. you would do a lot better with a scsi drive-

from a scsi drive you can do 6- 8 layers. because the access time is much faster- for most applications this is what people need.

also dont use 75% photojpeg you need to use 50-60% - believe me - the performance of photojpeg above 70% drops by 30% per layer - for no increase in anything. dont do it.
keep it below 75% at all times.
