You can't hot-swap drives with the onboard controllers, you can't add
and remove drives to the array (on the fly) with the onboard
controllers.. etc.

Oh, the kernel has let you do that for quite some time now.   RAID5 a
set of RAID5 arrays?  No problem.  :)

But in all seriousness, single drive transfer rates are exceeding 40
MB/sec, so you're rarely hurting for sustanied transfer speeds.  RAID0
doesn't boost average access times either -- because you're striping,
both drives generally need to be doing the same thing at the same time
so you can't have 'em seeking individually -- and that's what really
boosts performance.  Average I/Os per second.
