Software RAID does not scale too well I'm afraid (in my experience)

I find that software RAID is at least as good as basic "hardware" RAID
(unless you're paying at least three digits for a RAID card you're getting
software RAID anyway). I've used a number of RAID configurations over the
years and software RAID has caused me the least grief, not to mention that
I'm more confident that I should be able to recover the data if the server
dies and I have to move the drives to another machine with completely
different hardware.

Of-course software RAID isn't an option under Windows so there's still a
place for the cheap cards, and if you don't have the spare IDE channels
you'll need the card for that (I'd still disable RAID, though, and use
software RAID instead).
