Haven't actually run or seen one with a 3 disk RAID config.  Of course I'd 
much prefer 4 disks with the parity striping spread over 4 arms instead of 
the 2 arms a 3 disk config uses, but sometimes keeping cost down is very 
important (yes you're right - that RAID card add a chunk to the config - 
so another choice would be a 4 disk Mirrored config).  I can't imagine a 3 
disk RAID-5 config performing worse than a 2 disk Mirrored config.

Neil - we had a prev posting approx week ago about 3 disk raid
setups that seemed to be a performance problem, any comment?
Raid card and addtl disk adds over 30% to cost of box.
