Oh I do too ... even on database servers (at least whilst the
bottleneck is application inefficiency), but even with hardware RAID you
get around a 25% performance hit for RAID5(benchmarked on an untuned
system with a T3). I'd expect software RAID5 to be somewhat worse,
although I haven't benchmarked it.
