I have tried the DPT SmartRaid IV card (680X0 CPU, if memory serves) and it is a DOG performance wise. Using 4 18GB Barracudas (10k RPM) in RAID5 under Linux or NT I get about 3 MB/sec writes and 8 MB/sec reads.
I have seen much better numbers from the Mylex 960 line and particularly the ExtremeRaid line.

I think you meant 'if you're NOT really concerned about performance.'
The benchmarks I've seen for array controllers come nowhere near the
performance of a software-based array on a simple SMP server. For one
thing, the processor on, say, a DPT or ICP RAID controller is nowhere
near as powerful as an Intel Celeron, much less a DEC Alpha. Comments?
