My experience is that, as long as you're not using RAID5, they're
fantastic. The onboard RAID5 implementation however performs *very*
badly. Strangely the onboard RAID50 implementation performs just as
well as all the other options (including the misnamed RAID0).
Worth doing some simple performance benchmarking (dd if=/dev/sdX
of=/dev/sdX1 count=2000000) to get a rough indicator. Also worth
watching the WIO field of top to see if you're heavily I/O bound.
