It depends on your needs. If you have a system with lots of concurrent
activity, software RAID on IDE *will* be a bottleneck. There *are* good
reasons Adaptec why can sell their very pricey SCSI RAID controllers, and those
are all about performance.
If you're talking SCSI, I'm not sure how poor/well software RAID will perform in
comparison to hardware RAID, but I suspect a hardware controller will still win
if you're talking lots of concurrent activity.
In Pieters case it's a home multi-media system - one user presumably, mostly
single-threaded access. I think software RAID on IDE will probably do very
well.
