I've used a range of models from the older 2940/2940UW/2944 to 29x60.

Software raid was good enough when not using a raid level which required
cpu intensive computation (raid5 and equivalents). Not a real difference
to tell the truth.

My point is, i've never seen a single problem, they all run on a wide
range of hardware (AMD/Intel) and with a wide range of operating
systems (OS/2, different flavors of unix, windoze etc).

Indeed, my statement was a bit vague and i should have been a little more
specific.
