People who care about avoiding crummy manufacturer-proprietary disk
schemes care. People who resent having to buy the second card again to
get their data back if/when the first one fails care.
And, no, the HighPoint 1820A and Promise SATA150 TX4 cards don't have
the "same performance" as real hardware RAID: Only the XOR logic is
handled by a dedicated chip. All other RAID logic is offloaded to the
system CPU and OS.
