Not complaining at all, merely an observation.

It's a number of factors.  I've seen a lot of people who've spent
£200-300 on a RAID controller and been disappointed with the results.
For hardware RAID on a system where throughput was important I'd
expect to be spending at least £1000 on the RAID controller.

Perhaps the most worrying thing for me is those who think that RAID is
a replacement for a backup system - scary.
