While we are at it, disks being directly connected to the raid card will mean there won't be bus contention from nics and what not whereas software raid 5/6 would have to deal with that.
Could that really be an issue as well? What kind of traffic levels are we speaking of now? Approximately? That is to say, in as much this can be quantified at all.
I've never really seen this problem.
Oh yeah, we are on PCIe and NUMA architectures now. I guess this point no longer applies just like hardware raid being crap no longer applies because they are not underpowered i960/tiny cache boards anymore.
