SCSI disks tend to have faster seek times, so the latency might not be as

There is a softraid HOWTO (http://en.tldp.org/HOWTO/Software-RAID-HOWTO.html).
I'd be a bit wary about using IDE hardware RAID as (AFAIK) theres still no
standard for it, so if you trash your controller you might not be able to
get the data back.

I've used SCSI based HW and SW RAID under linux with no problems, but I
have not used them in situations where latency was important. Your likly
to be better off with a system and audio disk, like you said.
